摘要
给出了一种基于空时编码训练序列的信道估计算法,这种算法基于空时分组码的正交性。模拟实验证明,该算法适用于慢变瑞利衰落信道和时不变频率选择性衰落信道,同时该算法优干基于LS的算法。此算法可以应用于OFDM通信系统。
A channel estimation algorithm based on STBC-OFDM is given,which is based on the perpendicularity of space-time block code. A simulation experiment shows that the algorithm is appropreciate to slowly changed Rayleigh decay channel and non-time-varying frequency selected decay channel and it is optimal than Ls-based algorithm, it can be deployed in OFDM communication system.
