一种部分响应CPM信号的调制参数盲估计算法
A Blind Modulation Parameter Estimation Algorithm for Partial Responses CPM Signal
摘要
Abstract
A systematic scheme is proposed to solve the problem of modulation parameter estimation for partial responses CPM signal in non⁃cooperative communication environment.It can successively estimate carrier frequency,symbol rate,and modulation index and modulation order.After the estimation of symbol rate based on the features of cyclostationary of CPM signals,the joint estimation al⁃gorithm is simplified and a new cost function is constructed to estimate frequency offset and modulation index jointly.Lastly the modula⁃tion order is estimated by picking up features of cyclic spectrum line.Simulation results indicate that the algorithm can provide great per⁃formance under the SNR of 10 dB.关键词
