Error performance evaluation of DF cooperative IDMA systems over Weibull channels

In this study, bit error rate performance of interleave-division multiple access systems using decode and forward cooperative relaying technique are investigated. In the considered system, detection process is achieved based on chip-by-chip detection technique at relay and destination nodes. It is assumed that the channels between cooperating source, relays and destination nodes are subject to Weibull distribution. Bit error rate performance curves are obtained for different scenarios by using computer simulations.
