摘要

为有效利用载波索引差分混沌移位键控通信系统中参考信号的发射功率，提出了一种跳时短参考载波索引差分混沌移位键控通信方案。首先，将符号时间分成多个时隙后，根据参考索引比特取其中的一个时隙来发送短参考信号；然后，推导了所提方案在加性白高斯噪声信道和多径Rayleigh衰落信道下的理论误码率计算式。仿真结果表明，所提方案在频带利用率、系统能量效率以及误码率性能方面都有显著提升。

Abstract

In order to effectively utilize the transmission power of the reference signals in carrier index differential chaos shift keying (CI-DCSK)

a novel time hopping short reference carrier index differential chaos shift keying communication system was proposed.Firstly

the symbol time was divided into multiple time slots

one of which was selected to send short reference signals according to the reference index bits.Then

analytical bit error rate expressions over additive white Gaussian noise and multipath Rayleigh fading channels were derived.Simulation results verify that the proposed scheme has a significant improvement in spectral efficiency

system energy efficiency and bit error rate performance.
