摘要

给出了调制类型为M-PSK和M-FSK的信号符号率估计算法。估计M-PSK信号符号率的算法是基于信号复包络模的平方的傅里叶变换。估计M-FSK信号符号率的算法是基于原始信号的频谱分离成独立的子载波。算法仿真。结果表明，基于子载波分离的算法对通信信道噪声的敏感性较低。

Advanced algorithms for automatic symbol rate estimation of M-FSK and M-PSK signals

Algorithms for estimating the symbol rate of signals with modulation types M-PSK and M-FSK are presented. The algorithm for estimating the symbol rate of the M-PSK signals is based on the Fourier transform of the squares of the modules of the complex envelope of the signal. The algorithm for estimating the symbol rate of M-FSK signals is based on the separation of the spectrum of the original signal into separate subcarriers. Algorithms were simulated. It is shown that the algorithm based on separation of subcarriers is less sensitive to noise in the communication channel.
