In this paper, the bit error rate (BER) performance of multiuser multiple-input multiple-output (MIMO) systems over Rayleigh fading channels is studied, and corresponding asymptotic performance is analyzed. Based on the asymptotic analysis at high signal to noise ratio (SNR), using the probability density functions (PDF) of the instantaneous channel power gain, the diversity gain and coding gain of...
By combining adaptive modulation (AM) and automatic repeat request (ARQ), a cross-layer design (CLD) scheme for MIMO system with space-time block coding (STBC) and imperfect channel state information (CSI) is presented in this paper, and the effect of the imperfect CSI on the system performance is investigated. Based on the imperfect CSI, the probability density function of the effective signal to...
