摘　　要：无线信道中由于存在多径衰落,通信系统的可靠性会因此大大降低。增加收发两端的射频链路能够有效地解决这个问题,但射频链增加的同时又会提高成本。为此,提出一种基于发送端的递增改进算法,在不增加射频链路的前提下,完成对天线性能的鉴别,选择出对系统性能贡献最大的天线。仿真结果表明,该算法可有效地提高系统性能,减少系统检测时延。Since there exists muhi-path fading in wireless channels, reduced. Increasing the RF chains on both sides can solve the problem proposes an improved transmit antenna selection algorithm to identify the gorithm selects best antennas for the system performance. The simulation the reliability of the communication systems will be greatly effectively, but this method will raise the cost. This paper antenna performance instead of raising RF chains. The al- results show that the algorithm improves the system performance effectively and greatly reduces the system delay.
