End to end performance analysis of M2M cooperative communication over cascaded α-μ channels

In this paper, relay based mobile to mobile (M2M) system employing amplify and forward (AF) protocol has been considered and its end to end performance over N-α-μ fading channels has been explored. The closed form expressions for probability density function (PDF), cumulative distribution function (CDF) of cascaded α-μ fading channels and lower bound on average symbol error probability (ASEP) have been obtained. The analytical results have been confirmed by means of Monte Carlo simulations. The variation of the performance due to change in fading coefficients, relative geometrical gain, power allocation and number of cascaded components is also reported in this paper.
