基于概率的自适应跳频通信系统中的跳频图案产生方法
Frequency Hopping Pattern Generation Method in Probabilities-Based Adaptive Fre-quency Hopping Communication System
摘要
Abstract
To improve the reliability and security of underwater acoustic (UWA ) FH system ,a method producing frequency hopping (FH) pattern is presented based on bit error rates (BER) mapping and the quantification of pseudo random numbers .BER of all FH channels are mapped into the probability densi‐ty function (PDF) ,a quantitative vector can therefore be obtained .Furthermore ,the pseudo random numbers ,produced by the pseudo random number generator ,generate FH patterns according to the spe‐cific statistical rule and quantitative criteria ,which are used for FH communications .A specific adaptive FH communication simulation system based on probabilities is further established .Experimental simula‐tion demonstrates that the proposed method has a lower BER compared with the traditional FH or adap‐tive FH .Moreover ,it features better security performance .关键词
