摘要
在短波通信中,极低信噪比条件通信是一种应急通信手段.文章对极低信噪比条件下短波DS/SS系 统的设计原理和其中的几个关键技术作了较为详尽的介绍,并给出了关键性能指标的仿真结果.
In high frequency communication, extremely low SNR communication is an expedient means. This paper firt deals with the designing principles of HF DS/SS system for extremely olw SNR, then presents several results for key capability parameters.
