| 摘 要： | 提出了一种新的基于空域滤波和最大比合并的组合天线系统,解决了多用户无线通信中同时存在的共道干扰和衰落的问题,分析了存在任意功率的共道干扰时组合天线系统在Nakagami-m衰落信道下的中断概率和误码率的近似性能,通过与单纯的空域滤波或最大比合并比较可以看出,组合天线系统提高了多用户衰落信道的通信性能。证明了近似计算的有效性和近似性能表达式适用性更大。

| Abstract: | A new multi-antenna receiver is proposed based on Maximal Ratio Combing (MRC) and spatial filtering, which can solve the problems of both fading and co-channel interferences in multiuser mobile communication system. The outage probability and Bit Error Ratio (BER) approximate performance of multi-antenna system are analyzed in Nakagami-m fading channels with multiuser interferences. It is demonstrated that the new multi-antenna receiver improves the communication performance of multiuser system over fading channels through comparing with spatial filtering or MRC performance. |
