摘　　要：无碰撞区跳频序列在一定时延范围内序列间碰撞为零,在准同步跳频通信系统中具有广阔的未来。为降低跳频通信系统中因用户数增多而产生的频率干扰,本文实现了一种基于矩阵转换的无碰撞区跳频序列生成方法,并举例说明了构造过程,其无碰撞区范围和序列数量可灵活变动。同时本文构造了一种高复杂度RS(里德-所罗门)码作为比较,并仿真对比了两者在不同信噪比和用户数情况下的误码率。根据两者的构造理论和仿真结果,得出结论:在无碰撞区范围内接入跳频网络时,采用新型无碰撞区跳频序列比采用RS码的跳频通信系统误码率更低,大大增强了跳频系统的多址通信能力。The no-hit zone frequency hopping sequence is a sequence with zero collisions between sequences within a certain delay range,and has broad prospects in quasi-synchronous frequency hopping communication systems.To reduce frequency interference among users caused by the increase in user numbers in a frequency-hopping communication system,this article implements a no-hit zone frequency hopping sequence generation method based on matrix transformation,with variable no-hit zone range and sequence quantity,and illustrates the construction process with examples.At the same time,a high-complexity RS code was constructed as a comparison in this article,and the error rates of the two were compared through simulation under different signal-to-noise ratios and user numbers.The results showed that when accessing the frequency hopping network within the no-hit zone range,the hopping system using the no-hit zone hopping sequence had a lower error rate than the hopping system using RS code,greatly enhancing the multi-access communication capability of the hopping system.
