摘要
以8CPM为例,阐述了连续相位调制的原理,分析了CPM信号的调制方式及其性能的优越性,具体化连续相位调制过程,明确了用DSP实现的开销及可行性。同时对CPM信号捕获的方法进行了分析研究,提出了一种确实可行的捕获方案。在Matlab仿真的基础上,用DSP硬件平台实现CPM信号的调制、发送、接收、捕获,验证了捕获方案的可行性。
This paper takes 8CPM as an example to explain the principle of continuous phase modulation, analyze the modulation methods for CPM signal and its superiority, describes the details of the modulation process of CPM, and confirm the spending and feasibility of completing CPM with DSP. The acquisition methods for CPM signals have also been researched into, and a feasible acquisition scheme is proposed. On the basis of Matlab Simulation, the modulation, sending, receiving and acquisition of CPM signals are realized with DSP hardware platform, and the feasibility of the acquisition scheme is verified.
