跳频通信系统可靠传输控制技术的应用

Reliable controlled transmission for frequency hopping communication system

跳频系统发送端的载频受伪随机码控制,随机地改变载频以主动躲避干扰.在分析跳频通信系统技术特征的基础上,采用MATLAB研究了跳频通信系统可靠传输控制技术.研究表明:提高带宽B比增加信噪比S/N更能有效控制误码传输,同时讨论了差分跳频技术在提高通信系统安全方面的应用.

Frequency hopping system creates carrier frequencies controlled by pseudo-random codes which change at random and provide a flexible means to avoid interference actively.It is more reliable to increase bandwidth than to raise S / N.Differential frequency hopping in improving the safety aspects of frequency hopping communication system in securities was also discussed.
