摘　　要：最小频移键控(MSK)信号具有相位连续、包络恒定并且带宽占用小的优点,被广泛应用于现代无线通信领域。对MSK解调算法进行了分析总结,将MSK解调算法分为逐符号检测算法和多符号检测算法。根据这两大类检测算法的核心思想,对算法的误码率性能、运算复杂度及应用环境进行了详细分析,总结归纳了各检测算法的优点及存在的问题。实际工程中考虑到接收机的可靠性和成本因素,可以在误码率性能和复杂度之间选取一个折衷,采用合适的解调算法。MSK has the advantages of constant envelope and continuous phase, is widely used in wireless communication.The demodulations technologies including multiple symbol detection and symbol-by-symbol detection were analyzed in this paper. Furthermore, the performance simulation and algorithm＇s complication were compared with each other, and the advantages and the problems of these methods were summarized. Finally, considering the factor of actual applications and the cost, the appropriate methods could be adopted to reach a trade-off between performance and complicity.
