混合噪声环境下正交空时分组码误符号率的分析

Abstract

Abstract: The performance of orthogonal space-time block codes (OSTBC) is investigated in the presence of an additive combination of impulsive and Gaussian noises. Based on maximum likelihood (ML) decoding, an equivalent approximate model with mixture noise is constructed for multiple input single output (MISO) systems. By using the moment generating function-based analysis approach, the closed-form expressions for the average symbol error rate (SER) of OSTBC over Rayleigh flat fading channels are derived. Furthermore, the SER performance of the STBC is analyzed for different code matrices with M-PSK and M-QAM modulations. Monte Carol simulation results show good agreement with the analyses.

Key words: space-time block codes(STBC), symbol error probability(SER), mixture noise, multiple input single output(MISO)
