T1: Advances in Green Communications and Networks
Presented by: Zhisheng Niu, Professor, Tsinghua University, China
Time: 9:00–12:30
Room: 411

 

Abstract
The explosive development of ICT industry has emerged as one of the major sources of world energy consumption. As a result, having the information and communication networks more energy-efficient (green) is one of the most critical issues for a sustainable future of the whole world.

In this tutorial, we first claim that the networks planning and operation should be more energy-efficiency oriented and, in the meantime, the radio resources distributed over heterogeneous cellular networks should be optimized in a global way, i.e., Globally Resource-optimized and Energy-Efficient Networks (GREEN). Then, we propose two new frameworks called CHORUS (Collaborative and Harmonious Open radio Ubiquitous Systems) and TANGO (Traffic-Aware Network planning and Green Operation) for GREEN, aiming at increasing the energy efficiency from the system point of view while guaranteeing the coverage and optimizing radio resources as well. Some key technologies for the migration to CHORUS and TANGO are then presented and evaluated. Theoretical modeling and simulation studies show that the CHORUS and TANGO schemes can greatly improve the energy-efficiency of the cellular networks, while the quality-of-services (QoS) can be kept at a satisfactory level. In the end, this tutorial will give a comprehensive survey of the recent developments from algorithms to practical applications in green wireless communications, and summarize some open problems on critical energy-efficient design issues.

Tutorial Objectives
The objective of the course is to have the audience understand the background, challenges, research advances, and potential applications of energy-efficient communications and networks. Specifically, the course will
1) review the ICT development during the past 30 years (with major focus on Chinese market) and address the potential challenges when moving forward (especially from the viewpoint of energy-efficiency);
2) reveal the scientific issues and survey the recent advances in the research area of energy-efficient communications and networks;
3) discuss in details several potential paradigm shifts toward the green communications and networks, including TANGO (Traffic-Aware Network Planning and Green Operation) and CHORUS (Collaborative and Harmonious Open Radio Ubiquitous Networks);
4) provide some future directions.

Tutorial Outline

Primary Audience
Graduate students, post-docs, and any research engineers in the areas of electronic engineering, information and communication engineering, computer science and engineering, and telecommunication networks. Young faculties in the above-mentioned fields should also be benefited from the course.

Novelty
Green Communications and Networks is a relatively new research area, which has not been addressed in a systematic way in the past major IEEE Conferences as a tutorial. The two major novelties of this course are: 1) the review of the ICT development during the past 30 years (especially in China) and its grand challenges from the viewpoint of energy-efficiency; 2) the potential paradigm shifts by TANGO and CHORUS which are the original contributions from the instructor.

Presented by: S. Gaur, J. Acharya, L. Gao, Wireless Systems Research Lab, Hitachi America Ltd.
Time: 9:00–12:30
Room: 412

 

Abstract
In this tutorial, we provide researchers and academicians with an overview and insight into the deployment of heterogeneous networks for indoor and outdoor environments within the framework of 3GPP-LTE and LTE-Advanced. We demonstrate the need for heterogeneous networks in order to improve capacity and coverage of cellular systems. We discuss the underlying communication theory of such a network and discuss the interference coordination aspects. We cover the standardization efforts that have gone into incorporating heterogeneous network deployments within 3GPP. We present case studies of real world heterogeneous networks to illustrate the challenges and engineering performance trade-offs. In this tutorial we thus focus on core theory and network design aspects as well as business case for the operators to illustrate why heterogeneous networks are expected to be an integral part of current and future cellular systems.

Tutorial Objectives

Tutorial Outline

Primary Audience
People from academia and industry who are interested and involved in R&D and standardization of cellular systems.

T6: Turbo Equalization: Fundamentals, Information Theoretic Considerations, and Extensions
Presented by: Tad Matsumoto, JAIST, Khuorul Anwar, JAIST, and Norulhusna Ahmad, UTM
Time: 13:30–17:00
Room: 421

 

Abstract
This tutorial is started with a brief explanation of the basics of turbo equalization for broadband single carrier signaling, where sliding window technique is first introduced. Then, the sliding window formulation of the turbo equalization is converted into block-wise processing, with the aim of finally deriving a frequency domain equivalent of the algorithm.
For the Information Theoretic Considerations of turbo equalization, this tutorial introduces extrinsic information transfer (EXIT) chart as a useful tool for analyzing the convergence property of the turbo equalization.
This tutorial then extends the turbo equalization to time-concatenated chained turbo equalization (CHATUE), which connects turbo equalizers neighboring in time in the absence of cyclic prefix (CP) or guard interval (GI). The latest version of the frequency domain turbo equalization is utilized not only to mitigate the inter-symbol-interference (ISI) but also to eliminate the inter-block-interference (IBI) due to connecting the neighboring blocks.
Another application introduced in this tutorial is a new signaling technique, non-Orthogonal Frequency Division Multiplexing (n-OFDM), where turbo equalization is used to eliminate the inter-carrier interference (ICI) caused by intentionally overlapping the sub-carriers. This concept is analogous to the time-concatenated equalization technique described above. The main objectives of this technique are to achieve high spectrum efficiency and to improve the BER performance with n-OFDM, compared with the conventional OFDM system.

Tutorial Objectives
The primary goal of this tutorial is to provide the course taking with the in-depth knowledge of turbo equalization, its design techniques, and practical applications and its extensions. Each section however has its own objectives , which are all in common to help course taken build a technological basis presented in each section:
- Frequency Domain Turbo Equalization
First of all, this section shows that the key to achieving good performance of turbo equalization is to use random enough and long enough interleaver. Some of the mistakes found in recent publications are introduced and it is warned that such incorrect designs do not satisfy the principle of turbo coding. The main objective of this section is to provide lay knowledge for deriving the frequency domain processing to the course takers, with which the computational complexity of the turbo equalization is independent of the number of the multipath components in the channel.
- Information Theoretic Consideration of Turbo Equalization
The objective of this section is to provide the course taking with the information theoretic background of the turbo equalization techniques. The instructors have been motivated by reading some of the recent publications that use very strong code such as turbo and/or LDPC codes, but no significant iteration gain can be obtained. The reason for this is provided with warning statements from the viewpoint of the extrinsic information transfer (EXIT) curve matching. The doped accumulator lifts up the right most point of the EXIT curve of the equalizer to the (1.0, 1.0) mutual information point, by which we can avoid the intersection between the two curves, resulting in elimination of the error floor in bit error rate (BER) performance. It is also shown that even though very simple short memory convolutional code is used, still clear turbo cliff happens at a threshold SNR relatively close to the Shannon limit.
- Time Concatenated Turbo Equalization Systems
Time-concatenated/chained turbo equalization (CHATUE) is introduce which connects turbo equalizers neighboring in time in the absence of Cyclic Prefix (CP) or Guard Interval (GI), The latest version of the reduced complexity equalization technique, Frequency Domain Soft Cancellation Minimum Mean Square Error (FD/SC-MMSE) turbo equalization, is utilized not only to mitigate the inter-symbol interference (ISI) but also to eliminate the inter-block interferences (IBI) from the neighboring blocks. The algorithm derivation and the roles played by each component the are presented in detail. It is then show that the time-concatenated turbo equalization systems outperforms conventional CP-transmission and/or the other CP-free techniques in terms of BER performance, convergence property, and sensitivity to Doppler spread.
- non Orthogonal Frequency Division Multiplexing (nOFDM)
The turbo equalization concept is also used to eliminate the inter-carrier interference (ICI) caused by intentionally overlapping the sub-carriers, as is the equalization techniques for CP-free techniques. is analogous to the CHATUE algorithm. The main objectives of this section is first to introduce the nOFDM technique, and then to provide the course taker with the knowledge that how nOFDM systems with equalization can achieve high spectrum efficiency and improve the BER performance, compared to the conventional OFDM system.
