A weighted Alamouti (WA) media-based modulation (WA-MBM) scheme is presented. In this scheme, the real and imaginary parts of the diagonal and anti-diagonal WA codes are interleaved and transmitted according to a well-designed MBM channel states activation approach, so that the spatial resource units in both diagonal and anti-diagonal directions of WA-MBM signal are fully exploited to achieve higher spectral efficiency. The maximum-likelihood (ML) detection and theoretical average bit error probability (ABEP) for WA-MBM are derived. Simulation results demonstrate obvious performance improvement of WA-MBM over some existing MBM schemes.

基于加权 Alamouti 媒体的调制


提出了一种加权阿拉莫蒂（WA）基于媒体的调制（WA-MBM）方案。在该方案中，根据精心设计的MBM信道状态激活方法，对角和反对角WA码的实部和虚部进行交织和传输，使得WA的对角和反对角方向的空间资源单元-MBM信号得到充分利用，实现更高的频谱效率。推导了 WA-MBM 的最大似然（ML）检测和理论平均误码概率（ABEP）。仿真结果表明，WA-MBM 相对于一些现有的 MBM 方案有明显的性能提升。
