针对频率选择性信道下的放大转发协作通信，提出了一种观测窗长度可调的多分支联合检测器，并分析了其性能。与现有方法相比，该检测器能够根据每个分支的信道特性自适应地调整每个分支的抽头系数向量和OWL。仿真结果证实了分析，并显示了所提出的检测器对现有同行的优势。
In this letter, we propose an adjustable observation window length (OWL) multi-branch joint detector for amplify-and-forward (AF) cooperative communication under frequency selective channels and analyze its performance. In contrast to the existing methods, the proposed detector can adaptively adjust the tap coefficient vector and OWL of each branch according to the specific channel profile of each branch. Simulation results confirm the analysis and show the advantages of the proposed detector against existing counterparts.
