闭环二进制介质调制
Closed-Loop Binary Media-Based Modulation
AI总结：
本文通过解析分析证明开环二进制介质调制分集阶数仅为一，而闭环配置借助反馈和最优权重选择可实现分集阶数为二，且性能等效于Alamouti编码BPSK，仅需一条射频链。
摘要：
本文给出了单天线接收机在衰落信道下二进制介质调制（B-MBM）的解析结果。研究表明，在无反馈的情况下，开环B-MBM仅能实现分集阶数为一。然而，在闭环配置中，通过反馈和最优权重选择，可实现分集阶数为二。值得注意的是，采用解析计算最优权重的闭环B-MBM，其性能与Alamouti编码的BPSK传输等效，表明在存在反馈时，即使仅使用一条射频链也是可行的。
英文摘要：
Presenting analytical results for Binary Media-Based Modulation (B-MBM) over fading channels for single-antenna receivers. Illustrating that open-loop B-MBM, in the absence of feedback, only achieves a diversity order of one. However, with feedback and optimal weight selection in closed-loop configurations, a diversity order of two becomes achievable. Notably, the closed-loop B-MBM, with analytically computed optimal weights, performs equivalent to Alamouti-coded BPSK transmission, demonstrating feasibility even with just one radio frequency chain when feedback is available.
