摘要

研究了当使用混沌序列代替传统的伪噪声(PN)扩频码时，直接序列码分多址(DS-CDMA)的相干接收问题。采用分段线性映射(PWL)作为混沌扩展序列(CSS)。假设加性高斯白噪声信道(AWGN)。给出了单用户情况下误码率的解析表达式。

Analytical calculation of BER in communication systems using a piecewise linear chaotic map

The coherent reception of direct sequence-code division multiple access (DS-CDMA) is considered, when chaotic sequences are used instead of conventional pseudo-noise (PN) spreading code. A piecewise linear map (PWL) is used as chaotic spreading sequence (CSS). Additive white Gaussian noise channel (AWGN) is assumed. An analytical expression of the bit error rate in the single user case is presented.
