点击翻译按钮获取中文摘要

The primary objective of this proposal is the development of effective methods and algorithms essential for the future design of advanced broadband wireless packet data systems enabling bandwidth and power efficient high throughput access to the backbone telecommunication network for nomadic and mobile users of data and multimedia services. The techniques to be developed will be highly relevant to the design of all types of broadband wireless networks, including very high bit rate wireless local area networks (WLANs), but the main application target of the project are the fourth generation (4G) cellular radio systems and networks, and especially their future evolution. The scope of the proposal encompasses two major inter-related and presently rapidly developing areas in wireless communications: (1) reduced-complexity transceiver processing, resource allocation and user scheduling algorithms for multiuser MIMO and MIMO-OFDM cellular downlink through network coordination (also known as coordinated multipoint transmission/reception, or network MIMO); (2) MIMO multi-hop relaying and cooperative communication applicable to the cellular downlink.
