| 摘 要： | 本文提出了一种亲折ＤＰＳＫ信号的多码元差分检测方案,其复杂度随观察码元长度Ｎ仅呈线性上升,而Ｄｉｖｓａｌａｒ提出的最佳多码元差分检测实现复杂度随Ｎ呈指数上升＾［１］。分析与模拟结果表明：两者性能相仿。

| Abstract: | In this paper,a novel multiple symbol differential detection (MSDD) scheme is proposed.The complexity increases linearly with the number of observation symbols (N) while for the optimum MSDD proposed by Divasalar the complexity increases exponentially with N.The results of the analysis and computer simulations show that the performance of new scheme appoachs to that of optimum MSDD. |
