摘要
针对多入多出系统,研究了共信道干扰抑制能力提高途径,提出了一种turbo均衡方案:在不改变空时编码结构、不增加接收天线数量的条件下,能极大地提高空时编码多用户系统中共信道干扰抑制能力。仿真结果显示,在存在一、二个主域共信道干扰时,该方案能明显降低误码率。
In this letter, we propose a soft/cancellation turbo equalization scheme to suppress cochannel interference（CCI） in space code systems. It is shown that the proposed method can effectively suppress CCI while preserving the space-time structure, without increasing receiver antenna, thereby significantly improving the system＇s interference suppression ability. The results of simulation express that the scheme can depress error bits rate when there is one or two CCI in the system.
