本文针对调频差分混沌移相键控FM-DCSK数字通信中误比特率问题进行了研究
通过分析相邻两比特间的调制信息与符号函数的关系
提出了一种改进的相关估算解调方法.仿真结果表明
在不降低传输速率的前提下
较以前调频差分混沌移相键控调制方式
误比特率有明显改善.
This paper presents a kind of improved method of correlation estimation demodulation in order to solve the problem of bit error rate of FM-DCSK in digital communication
through analyzing the relation between modulation information and symbol function of two adjacent bits.Simulation results show that the bit error rate is obviously improved in comparison with the former FM-DCSK system under the condition of the same transmission efficiency.
