摘要
MSK信号具有包络恒定、相位连续的优点,被广泛应用于无线通信领域.笔者对MSK信号的解调算法进行了分析总结,将MSK信号的解调算法分为最大似然序列检测法、逐码元检测法;综述了这两类算法的原理,并分析了其优点及存在的问题,然后对这些解调算法进行系统仿真及运算复杂性比较.文章最后结合MSK信号的应用前景分析了突发MSK信号的解调技术.
MSK has the advantages of constant envelope and continuous phase,is widely used in wireless communication.The demodulations technologies include maximize likelihood sequence detection and symbol-by-symbol detection,in this paper,these methods are analyzed,the performance are simulated and compared with MCRB.Based on the future applications of MSK,the research direction of demodulation technologies is presented in the end.
