摘要
Alamouti编码是一种多天线分集编码。该编码能在不增加功耗的前提下为系统提供增益的同时,获得非常低的复杂度。文章首先对多天线Alamouti编码方式进行推导。然后在瑞利衰落信道下对Alamouti编码和QPSK调制的多天线系统进行性能仿真。仿真结果表明,在瑞利信道下Alamouti码可以为无线系统提供良好的分集增益。
Alamouti coding is a multi-antenna diversity code. This code can provide performance gain for communication system without increasing power consumption. In addition, it has very low coding and decoding complexity. In this paper, after analyzed Alamouti coding, the performance of Alamouti coding via Rayleigh channel is simulated. The simulation results show that Alamouti coding can achieve much diversity gain in the Rayleigh fading channel.
