| 摘 要： | 重点研究垂直分层空时编码技术的几种检测算法,分析最大似然译码算法、QR分解算法以及基于迫零准则和基于最小均方误差准则的两种经典估计算法。为了进一步降低系统误码率,讨论两种经典估计算法与排序逐次干扰消除相结合的方法。MATLAB所得仿真结果表明,将经典检测算法与排序逐次干扰消除相结合,可以提高系统误码率性能。

| Abstract: | Detection of algorithm vertical stratification space-time code technology（VBLAST） is studied.Classical detecting techniques including QR detecting method,zero forcing（ZF） detecting method and minimum mean square error（MMSE） detecting method are investigated.In order to further reduce the BER,the two kind of classical algorithms combined with sorting serial interference eliminate（OSIC） method are discussed.Finally,the simulation results are given.The results show that it improved the system performance. |
