针对跳频通信中传统收发同频体制的不足,介绍了一种新的增加可用频率数的方法。提出了不对称频率表的概念及设计,对其在短波跳频通信中提高跳频处理增益、改善系统抗阻塞干扰等性能进行了分析,并与常规跳频进行了比较,得出了一些有益的结论。
Aiming at the shortcomings of the traditional system of transmitting and receiving frequency in frequency hopping communication, a new method to increase the number of available frequencies is introduced. The concept and design of asymmetric frequency table are presented. The performance of frequency hopping gain in shortwave frequency hopping communication and the improvement of anti-jamming performance of the system are analyzed and compared with conventional frequency hopping. Some useful results are obtained Conclusion.
