摘要: 非正弦波调制信号存在相位突变,在工程实践中易产生较大的冲击电流,给大功率发射系统带来较大困难;而且相位不连续也不利于保持正交脉冲间的正交性,不利于信息的正确解调。针对该问题,提出了解决方案:基于无抖动编码的非正弦波调制。该方案用平滑的波形来替换前后码元的不连续跳变,从而得到相位连续的时域波形,波形平滑、频谱主瓣窄、滚降速度快。

Abstract: There is abrupt phase change in nonsinusoidal waves modulation.It can easily produce impulse current and bring large difficulty to high-power emission system;so it is not beneficial to holding the orthogonality between the orthogonal pulses and demodulating information.For this question,nonsinusoidal wave modulation based on IJF coding is put forward.This scheme uses smooth wave instead of discontinuous wave,so the wave in time field is continuous phase and has good frequency spectrum characteristics.
