Convexity properties of outage probability under rayleigh fading
2012 20th Signal Processing and Communications Applications Conference (SIU), 2012 In this paper, convexity properties of outage probability are investigated under Rayleigh fading for an average power-constrained communications system that employs maximal-ratio combining (MRC) at the receiver. By studying the first and second order derivatives of the outage probability with respect to the transmitted signal power, it is found out ...
