一种实用的MPSK／TDMA突发信号盲解调方案
A Practical Scheme for Blind Demodulation of MPSK/TDMA Burst Signals
摘要
Abstract
In view of TDMA target signal parameter completely unknown,a kind of blind demodulation scheme of MPSK/TDMA burst signals is put forward.In this scheme,a blind detection algorithm based on unique word is used to correctly detect burst signals,an improved modified covariance method is used to accurately estimate the carriers,and a nonlinear transformation algorithm is used to ac⁃curately estimate the symbol rate of MPSK signal.A feedforward method with carrier synchronization and code synchronization algorithm is designed to realize blind demodulation of MPSK/TDMA burst signals.The theoretical analysis and simulation experiment results show that this scheme has better performance in engineering application.关键词
