摘要
探讨了连续相位调制技术,提出了基于CPM技术的应用实例,任何连续相位调制器均可分解为无记忆调制器和连续相位编码器,该技术具有较高的功率和频谱利用率.采用多元码和CPM调制技术相结合实现的串行级联系统,既降低了CPM系统成本,又提高了系统性能,具有较大的实用价值.
Based on the analysis of continuous-phase-modulation technique, this article has brought forward examples of application. Any CPM moulator can be listed as a memoryless modulator and a continuous phase encoder. This technique has the advantages of high efficiency of power and high efficiency of spectral. It is especially practical to combine poly-cell code with CPM and it can reduce system cost and raise function.
