The performance of a multiple-input-multiple-output (MIMO) code-division multiple-access (CDMA) system, using space-time spreading (STS), is analyzed over a frequency-flat Nakagami-m fading channel. The convolutionally space-time coded system employs a decorrelator detector with N = 2 and L antennas at the user side and base station (BS), respectively. Assuming independent Nakagami fading channels...
In this paper we derive closed-form expressions for the single-user capacity of selection combining diversity (SCD) system, taking into account the effect of imperfect channel estimation at the receiver. The channel considered is a slowly varying spatially independent flat Rayleigh fading channel. The complex channel estimate and the actual channel are modelled as jointly Gaussian random variables...
The performance of a multiple-input multiple-output (MIMO) code-division multiple-access (CDMA) system, using space-time spreading (STS), is examined over a frequency-flat Nakagami-m fading channel. The convolutionally space-time coded system employs a decorrelator detector with N=2 and L antennas at the user side and base-station (BS), respectively. Considering binary-phase-shift Keying (BPSK) transmission,...
In this paper, we propose a robust STBC transmission scheme to combat the timing synchronization errors over frequency-selective multiple-access channels. First, the equivalent channel model in the presence of timing synchronization errors is derived and we find that the synchronization errors result in an equivalent channel model with larger number of correlated channel taps. Based on this correlated...
