| 摘 要： | 文中对连续相位调制信号的解调算法作了相关研究。阐述了如何在信号状态网格图的基础上应用维特比算法对信号进行解调,并分析了最大似然序列检测和基于判决反馈的减少状态序列检测这两种序列检测方法,仿真结果表明,基于判决反馈的减少状态序列检测能在几乎不损失误码性能的前提下大大减少解调运算量。

| Abstract: | This article introduces the demodulation of Continuous Phase Modulation signal based on Veter-bi algorithm, and analyses the Maximum- likelihood sequence detection and the Reduced state sequence detection with decision feedback. Simulation results show that the reduced state sequence detection with decision feedback can effectively reduce the computational complexity with no loss of error performance. |
