Abstract :
In this work, first, we deduce the probability density function (PDF) and the cumulative distribution function (CDF) of the fading coefficient envelope, based on the correlated modified Weibull fading model. To simply the discussion, a system with two transmit antennas and one receive antenna is considered, namely dual-branch system. Secondly, the outage probability of the dual-branch system under the correlated modified Weibull fading channel is derived. And the effects of the correlation coefficient and the Weibull fading parameter on the performance are analyzed by computer simulation for QPSK modulation. Finally, we present several simulations to validate our analysis. Results show that the simulation curves fit our analytical results correctly
