摘要

本文提出了在多径衰落信道上与一类连续相位调制(CPM)信号耦合的栅格码。介绍了相干、差分相干和非相干检测的接收机结构。给出了所考虑系统的仿真结果。结果表明，差分相干系统虽然性能比相干系统差，但为栅格编码的CPM提供了最可行的接收结构

Class of compact spectrum coded signals over multipath fading channel

The author presents a trellis code coupled with a class of continuous phase modulation (CPM) signals over a multipath fading channel. Receiver structures for coherent, differentially coherent, and noncoherent detection are presented. Simulation results for the systems under consideration are shown. It is concluded that the differentially coherent system, though inferior in performance to the coherent system, offers the most feasible receiver structure for the trellis-coded CPM over a Rician fading channel.<>
