This paper uses a simple closed-form technique for the computation of the symbol error rate or bit error rate for the performance of coherent M-ary digital modulation schemes over Nakagami-m fading, Rician fading and perturbed by additive white gaussian noise . The expressions for the symbol error probability or bit error probability are simple and include Gauss hypergeometric functions which can...
In this paper, we investigate the impact of channel estimation error on the average symbol error probability (SEP) of multiple-input multiple-output maximal-ratio combining (MRC) systems in the presence of cochannel interferences (CCIs) in Rayleigh fading channels. Using an accurate exponential bound for the Gaussian Q-function, we present a simple approximate solution for the average SEP of general...
In this paper we derive optimal power allocation (PA) in space and time that minimizes BER for transmitter selection in multi-input-single-output (MISO) Rayliegh fading channels assuming perfect channel state information (CSI) is available at receiver and transmitter. This power allocation scheme achieves exponential diversity order with a single RF front end and requires feedback of the best channel...
