针对非正弦通信系统调制解调器实现的问题,在分析相关原理和Sundance开发平台及其开发环境特点的基础上,提出了以PSWF为调制波形、以时域正交调制为调制方法的非正弦调制解调器设计与实现方案.该方案采用模块化的设计思想,将系统划分为若干功能独立而又相互关联的任务模块,通过对各个任务模块的设计来完成系统设计.结果表明,该方案可以实现信息的非正弦调制解调.为设计高性能的非正弦通信系统提供了一种有效的方法.%For the issue of the realization of non-sinusoidai modem, the characteristics of relevant principles and the Sundance development platform and development environment are analyzed, then a method to design and realize the non-sinusoidal modem which take PSWF as the modulate waveform and time-domain orthogonal modulate as the modulate approach is proposed. A modular design concept was used in the method, and the system is divided into several functional independent but interrelated modules, the system design was completed through the design of the various task modules. The result indicated that the method realized the information non- sinusoidal modulation and demodulation, and it provides an optimal solution to the design of high-performance non-sinusoidal communication system.
