摘要 对于3个用户的多输入多输出干扰信道,提出一种无反馈的干扰消除方法。为每个用户设计具有Alamouti结构的空时码字,通过在码字中引入零矩阵,消除第3个接收端的多用户干扰,同时减少第1个接收端和第2个接收端的多用户干扰。利用Alamouti码字对应的等效信道矩阵的正交特性,消除第1个接收端和第2个接收端的多用户干扰。与相同场景中的已有方案相比,所提方案无需反馈信息,并且保持了相同的传输效率。 Interference cancellation method without feedback is proposed for Multi-input Multi-output （MIMO） interference channel with three users. Space-time code with Alamouti structure is designed ofr each user. The multi-user interference at the third receiver is cancelled by introducing zero matrices into each code, and the multi-user interference at the other two ceceivers is eliminated by the orthogonal property of Alamouti code. Compared with existing schemes for the same scheme, the proposed scheme requires no feedback information and maintains the same transmission efficiency.
