A Novel Symbol Rate Blind Estimation Algorithm for Multi-h CPM Signal
Tao Zhang · Telecommunication Engineering · 2012
A low complex algorithm for symbol rate estimation of Multi-h CPM(Continuous-Phase Modulated) signal is presented.The main contribution in this paper is that a prefilter and square estimator is derived and its principle is explained using PAM decomposition of Multi-h CPM signal.Computer simulation results show the unbiased estimator is robust and it does not need prior informations of carry frequence and modulate index.
