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.

本提案的主要目标是开发有效的方法和算法，这些方法和算法对于先进宽带无线分组数据系统的未来设计是必不可少的，该系统能够为数据和多媒体服务的游牧和移动的用户实现对骨干电信网络的带宽和功率高效的高吞吐量接入。这些技术将与所有类型的宽带无线网络的设计高度相关，包括非常高比特率的无线局域网（WLAN），但该项目的主要应用目标是第四代（4G）蜂窝无线电系统和网络，特别是它们的未来发展。该提案的范围包括无线通信中两个主要的相互关联且目前快速发展的领域：（1）通过网络协调降低多用户MIMO和MIMO-OFDM蜂窝下行链路的收发器处理、资源分配和用户调度算法的复杂度（也称为协调多点发送/接收，或网络MIMO）;（2）适用于蜂窝下行链路的MIMO多跳中继和协作通信。
