ELEC6252 Future Wireless Techniques

Module Overview

This course covers some advanced techniques that have the potential for application in the future generations of wireless communications systems. Recently, the research and development in wireless communications have been focused on the techniques for the fifth generation (5G) wireless systems. Therefore, this course will cover a few of the key techniques proposed for the 5G wireless systems. The course begins with the principles of cooperative communications. A range of relay and cooperative networks with different relay protocols are considered. One-hop, two-hop and multiple-hop networks with one or multiple cooperative nodes are analysed. Cooperative protocols may include amplify-and-forward, decode-and-forward, compress-and-forward, network coding, etc. Furthermore, some fundamentals in multicell cooperation are discussed. Then, the course considers the principles of full-duplex, addressing the self-interference cancellation techniques for full duplex systems, and examines the potential of full-duplex for wireless system design. Next, the course’s focus is on the non-orthogonal multiple-access (NOMA), which is a technique allowing densely deployed users (devices) to simultaneously transmit their information. The NOMA principles are analysed in the context of both the uplink transmission and downlink transmission. Then, the course moves to the principles of multiple-input multiple-output (MIMO), followed by analysing the potential of MIMO for meeting the requirements of future wireless systems. A range of technical options for MIMO transceiver optimisation are also discussed. Built on the above theoretical foundation, the course then covers the multi-user MIMO and massive MIMO, with the emphasis on their principles, characteristics, and implementation challenges. The final part of the course covers the millimetre wave (MmWave) communications. This part first provides an overview of MmWave communications. Then, it exams the fundamentals of ultrawideband (UWB) communications by considering issues such as, UWB signalling, modulation, coding, equalisation, etc. Next, it characterises the MmWave channels with the emphasis on its differences from the conventional radio frequency (RF) communication channels. The course concludes with the MmWave transceiver design, covering mainly the beamforming techniques operated in the analog, digital or hybrid analog-digital domain.
