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. In this paper, the continuous phase modulation technique is discussed and an application example based on CPM technology is proposed. Any continuous phase modulator can be decomposed into a memoryless modulator and a continuous phase encoder, which has higher power and spectrum utilization. And CPM modulation technology to achieve a serial cascade system, which not only reduces the CPM system costs, but also improve system performance, with great practical value.
