摘要 利用分组干扰抑制的方法,通过合理地设计空时码的发射码矩阵和对阵列天线进行了子阵划分,提出了一种新的混合型的空时编码方法。新的编码方法结合了空时分层码(BellLayeredSpace-TimeArchitecture:BLAST)和空时分组码(Space-TimeBlockCoding:STBC)的特点,相对于空时分层码而言,新方法在同样的信噪比条件下可以取得明显低的误码率。相对于空时分组码而言,新方法具有更高的频谱利用率。 A new hybrid space-time coding approach is presented in this paper. The properly designed code matrix and group interference suppression method are used in this approach. The new coding approach which combines BLAST and STBC, compared with BLAST, performs with a distinctly low BER on the same condition of SNR. And compared with STBC, the coding approach we proposed performs with a higher efficiency of frequency.
