摘要： 高频通信通常应用在较远距离的通信中，因为它的架设成本低，变化灵活，抗干扰的能力也很强。其信道为多径衰落信道，因此对该信道的特性仿真近几十年来都十分活跃。文中研制的软件仿真器利用计算机的声卡实现对基带信号的信道仿真，是一个低成本的设计，能够全面地反映多径衰落信道的多径时延、多普勒频移、多普勒扩展等特性。

Abstract: High-frequency communication plays a vital role in long haul communications, on account of its unique merits such as low cost, convenience to be generated and strong resistance to damage. The high-frequency communication channel is a multipath and fading channel which has been studied for quite a time. Software simulator presented in this paper achieves the simulation of baseband with the sound card of computer, which costs a little and well represent various features of multipath and fading channels such as Multi-path delay, Doppler shift, Doppler spread, etc.
