The performance of spatial multiplexing-based multiple-input multiple output (MIMO) systems using zero forcing (ZF) detector in frequency selective fading channels is analyzed in this paper. The approximation of a linear combination of Wishart matrices is used to derive the probability density function (p.d.f.) of output signal-to-noise ratio (SNR) expression. Analytical error rate expressions for...
In this paper, the performance of vertical Bell labs space-time (V-BLAST) algorithms for the MIMO systems with two transmit antennas is analyzed over correlated-Rayleigh channel. We derive the analytical bit error rates (BERs) of the first and second detection steps for both optimal and fixed detection ordering schemes. We also investigate the signal-to-noise ratio (SNR) degradation of the detection...
In this paper, we investigate MIMO systems with transmit antenna selection over an intra-class correlated Rayleigh fading channel. In our study, one single transmit antenna with an aim to maximizing the total received signal-to-noise ratio (SNR) is selected for transmission, while it is assumed that the receive side use all the available antennas. Using binary-phase-shift-keying (BPSK) modulation...
In this paper, the capacity of multiple-input multiple-output (MIMO) systems over a Rician fading channel is evaluated. We show that the capacity of MIMO Rician channels can be well approximated by that of correlated MIMO Rayleigh channels. We take the Rician channel with rank-1 mean matrices as an example, the asymptotic capacities at low and high signal- to-noise ratio (SNR) regions are analyzed...
In this letter, a new form of bivariate gamma distribution is proposed from the complex inverse Wishart matrix. We have derived the closed-form expressions for the probability density function and the joint central moments of this bivariate gamma distribution. Finally, the analytical results are used to obtain the outage probability for a multiple-input multiple-output wireless communication systems...
