短波软件无线电系统的研制

以单功能语音传输短波电台为基础，建成了一个短波软件无线电系统，并在该系统上对软件无线电的某些关键技术进行了深入研究．实验结果表明，在单功能通信系统中引入软件无线电技术，可获得一个可靠、灵活、业务升级便捷的多功能通信系统，而且系统具有完全的可编程性，可在保持硬件体系结构简单化和标准化的同时，通过不同的软件，实现不同的系统功能．

Development of the HF Software Radio System

Based on the HF transceiver, a HF software radio system is developed. Andsome key technology about software radio is researched thoroughly. the experimentresult shows that a new communication system, which is reliable, flexible and easy torenew, can be setup by applying software radio technology into a generalcommunication system. The new HF software radio communication system isprogrammable, and it can perform various functions by varying the loaded-softwarewhile remaining its hardware structure simple and standardized.
