摘要
首先介绍了MSK信号差分检测原理。其次,分析了存在相关高斯噪声和信道有瑞利衰落时MSK的抗噪声性能。结果表明,在高斯噪声时的差分MSK的误码率与DPSK相同;而当信道存在瑞利衰落时将严重影响系统的抗噪声性能。所得结论能为系统的设计提供重要依据。
In this paper, we introduce the detecting principle of MSK.Then we discuss performance of bit error rate (BER) of MSK in the presence of Gaussian noise and Rayleigh fading of transmission. The results show that BER of the differential MSK is the same as DPSK existing correlating Gaussian noise, and the Rayleigh fading of channel will gravely worse the BER of system. The conclusion can give important reference.for the system design.
