软件法实现的实时高频信道模拟器

A Software-based Real-time HF Channel Simulator

随着数字信号处理芯片的发展，用处理芯片和软件实现实时高频信道模拟器已成为可能．本文研制了一种4kHz带宽的基带实时高频信道模拟器，采用了高速数字信号处理芯片TMS32010，并用PC机完成人－机对话，因此它的用户界面是良好的．本模拟器可用于高频通信机的调试中．

The softaware-based real-time High Frequency(HF) channel simulator has been realizable along with the development of digital signal processing (DSP) chip. In this paper, we describe one such simulator of 4kHz signal bandwith based on DSP TMS32010, adopting PC fulfiling user interface. This simulator can be used in testing HF communication equipment
