| 摘 要： | 基于对信道容量公式的分析,得到了增加一对发射与接收天线时信道容量增量的表达式,通过对该表达式的分析简化提出了当发射端与接收端射频链路数相同时的低复杂度联合发射与接收天线选择(JTRAS)算法.仿真结果表明新算法在计算复杂度较低的条件下性能优于目前存在的其他算法,与最优算法接近.

| Abstract: | Based on the analysis of the channel capacity, the equation about the increase of the channel capacity was de-rived when one more pair of transmit and receive antennas were added. By analyzing this equation, a joint transmit and receive antennas selection algorithm with low complexity were proposed when there were the same number of RF chains at both of the transmitter and receiver side. The simulation results illustrate that the new algorithm outperforms the other existing algorithms with lower complexity and it approaches the optimal algorithm most. |
