Abstract

Outage probability (OP) of amplify-and-forward direct-sequence code-division multiple-access (DS-CDMA) systems is analysed with best path selection over α − η − μ fading channels. First, cumulative distribution function (CDF) of α − η − μ fading is derived and then, lower bound of the OP is obtained for the considered system. An asymptotic CDF expression is also proposed in order to get more insights on system behaviour. The OP performance is presented for different relay and fading parameter configurations. Analytical derivations are validated by the close agreement with simulations.
