Methods and algorithms for spectrally efficient broadband wireless networks

这项提议的主要目标是开发对未来先进的宽带无线分组数据系统的设计至关重要的有效方法和算法，使数据和多媒体服务的游牧用户和移动用户能够高效、高功率地接入主干电信网络。将要开发的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，特别是它们的未来演进。该提案的范围包括无线通信中两个相互关联且目前快速发展的主要领域：(1)通过网络协调(也称为协调多点发送/接收，或网络MIMO)，用于多用户MIMO和MIMO-OFDM蜂窝下行链路的降低复杂性的收发处理、资源分配和用户调度算法；(2)适用于蜂窝下行链路的MIMO多跳中继和协作通信。

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.
