摘要
文章基于进一步提高跳扩频通信系统的抗干扰性能，提出了在混合直接序列扩频（DS／SFHCDMA）通信系统中实现自适应跳频（AFH）方式，给出了基于优化考虑的自适应跳频地址编码方法，在给出信道仿真参数的前提下，对自适应跳频系统的误码性能进行了分析。结果表明自适应方式优于传统方式。
in order to increasc the performance of direct-sequence/slow frequency hopping code division mutiple-access (DS/SFH CDMA)systems,a hybrid DS/SFH CDMA with adaptive frequency hopping (AFH)is proposed. The method of adaptive FH coding is considered as a optimization problem, The performancc of the system is examined. Simulation results show that biterror probability of AFH system is bctter than the SFH system.
