摘要
空时分组编码-正交频分复用(STBC-OFDM)系统是未来移动通信的研究热点。协同网络利用空间可获得的分布式天线,从而获得额外的空间分集增益。把协同分集应用到空时分组编码-正交频分复用系统中,给出一种新的协同空时块码OFDM系统。采用放大前传、译码前传和处理前传3种协同策略,研究在不同协同策略情况下的最大接收机机构和系统性能。
Space-time Block Coded OFDM （STBC-OFDM） system is a hot topic in future mobile communications.Collaborative networks may use distributed antenna space to obtain additional space diversity gain.In the paper,cooperative diversity is applied in STBC-OFDM systems.Using three cooperative strategies of amplify-and-forward,decode-and-forward and process-and-forward,the best receiver structure and system performance in different collaborative circumstances are studied.
