协作通信网络中的合作编码技术

未来觅带无线通信系统要支持高达1 Gb／s的峰值无线传输速率，就必须考虑利用协作通信技术，充分复用频率、时间、空间等多维资源，改善网络覆盖性能。合作编码将协作信号处理和信道编码技术有机地结合在一起，是实现高性能合作通信的重要保障，合作编码将成为未来觅带无线通信技术的一项关键技术。合作编码技术必须适应节点的双工或半双工通信方式，采用适应不同的协同通信网络环境要求的合作编码技术方案。未来的合作编码技术的发展方向是自适应的合作编码技术和网络编码协作技术。

Coded Cooperation Techniques in Collaborative Communication Network

In order to support the high data rate up to 1Gb/s in the future broadband wireless communication system, collaborative communication should be employed to improve the effective network coverage by fully reusing the limited multidimensional resources such as the frequency, time and spatial resources. As a reasonable combination of the collaborative signal processing and the error control coding technology, coded cooperation could be utilized to secure the collaborative communication with high reliability, and therefore is one of the most important enabling techniques for the broadband wireless communications in the near future. It is shown in this paper that the practical implementation of some specific coded cooperation scheme is dependent on either the full duplex communication or the half-duplex communication is used. Moreover, the choice of the coded cooperation schemes should be suitable for the specific network communication model and environment. It is concluded that adaptive coded cooperation and network coded cooperation are two promising deployment settings in the future applications.
