摘　　要：多指数连续相位调制(Multi-hCPM)是一种有效的恒包络调制技术,由于其相位连续的特性,信号带宽较小。利用ML方法在Walsh信号空间中进行Multi-hCPM符号定时和载波同步的联合估计,为了有效地界定该方法,还推导了Multi-hCPM的修正的CROB边界。仿真表明,该方法具有良好的性能。Multi-h Continuous Phase modulation （Multi-h CPM） is an effective constant envelope modulated technique, and the signal＇s band is narrow because of its continuous phase. The symbol timing and carrier phase were jointly estimated in Walsh signal space by virtue of ML method. The MCRB bound of the Multi-h CPM was deduced for evaluating the performance. The simulations demonstrate the method has the better performance.
