Continuous Phase Modulation Digital Signaling

连续相位调制（CPM）是一种恒定包络数字信令方案，与标准调制格式相比，它可以减少频谱占用和/或提高性能。关于如何执行接收到的CPM信号的载波相位跟踪以便提供相干参考的信息很少。本研究计画的第一个目标是推导并分析一种适用于一般多进制部分响应CPM调变的载波追踪系统架构。第二个任务将确定一组CPM调制参数，它同时优化性能和最小化实现复杂性，并将用于在第一个任务中所需的计算机模拟。

Continuous phase modulation, CPM, is a constant envelope digital signaling scheme which promises reduced spectral occupancy and/or improved performance when compared to standard modulation formats. Little information is available on how to perform carrier phase tracking of a received CPM signal in order to provide a coherent reference. The first goal of the proposed research program is to derive and analyze an architecture for a carrier tracking system which is applicable to the general M'ary partial response CPM modulation. The second task will identify a set of CPM modulation parameters which simultaneously optimizes performance and minimizes implementation complexity, and which will be used in the computer simulations required in the first task.
