Abstract In this paper, the performance of L-branch selection combining receiver over correlated Weibull fading channels in the presence of correlated Weibull-distributed cochannel interference is analyzed. Closed-form expressions for probability density function and cumulative distribution function of the signal-to-interference ratio at the output of the selection combining receiver present main contribution of this paper. Numerical results are also presented to show the effects of various parameters as the fading severity, correlation and number of branches on outage probability.

BPSK and QPSK non-linear satellite communication system performance in the presence of cochannel interference

Abstract Taking the uplink and downlink cochannel interference and noise into account, the analytical expressions are derived for determining the bit error probability in detecting a binary phase-shift-keying (BPSK) and a quaternary phase-shift-keying (QPSK) Gray coded signal, transmitted over a satellite system exhibiting amplitude modulation-to-amplitude modulation (AM/AM) conversion effects and amplitude modulation-to-phase modulation (AM/PM) conversion effects. On the basis on the derived theoretic formulae, using real-life system parameters, numerical results are obtained and presented. We point out the explicit comparisons of satellite communication system performance obtained when a satellite transponder amplifier is modelled by a hard-limiter and those obtained when both AM/AM and AM/PM non-linearities of the satellite transponder amplifier are taken into consideration.
