基于SIMO系统的RA-CDSK通信方案性能分析
Performance analysis of RA-CDSK communication scheme based on SIMO system
摘要
Abstract
For the issue of channel fading in wireless communication, a single-input-multiple-output reference-adaptive correlation-delay-shift-keying (SIMO-RA-CDSK) system was proposed. Gaussian approximation method was adopted to obtain the exact performance analysis and the BER formula derivation of SIMO-RA-CDSK system over additive white Gaussian noise (AWGN) channel and Rayleigh flat fading channel. All the analytical results were validated by Monte Carlo simulation. The results show that compared with traditional chaotic communication systems, the scheme not only decreases the intrasignal interference component and noise component during the demodulation, but also obtained the useful signal component gain from the multiple receiver antennas. The bit-error ratio (BER) of SIMO-RA-CDSK decreases with the increase of the number of receiver antennas, and that due to less intrasignal interference and noise interference in SIMO-RA-CDSK, with the same number of receiver antennas, the BER performance of SIMO-RA-CDSK system is better than that of SIMO-CDSK (single-input-multiple-output CDSK) system.关键词
