Abstract :
In this work, bit error rate performance of direct-sequence code-division multiple access systems is investigated by using amplify-and-forward method. First, all channels between source, relays and destination are assumed to be Weibull distributed. Then, the source-destination channel is considered to experience Rayleigh fading while the other channels are subject to Weibull fading. Bit error rate performance is obtained by varying the number of relays and the value of fading parameter by means of computer simulations.
