Outage probability analysis in relay-based DF cooperative diversity systems with relay destination interferers

摘要

Incremental relaying was firstly introduced in order to accommodate for the restriction associated with the fixed relaying schemes by using the intermediate relays only when they are needed by using a feedback from the destination to determine whether or not to use the relay which depends mainly on the usability of the direct path between the source and the relay. When the relay receives this negative feedback from the destination then it will send the signal to the destination within the second time slot which by then will be combined with the source signal using MRC, and by this, the system resources will be utilized efficiently. This paper provide the performance analysis of a decode-and-forward incremental relaying cooperative relaying over Rayleigh and Nakagami-m mixed fading channels with the presence of multiple interferers L and N near the destination and the relay respectively, which in turn will degrade the overall system performance and also compares the system performance with and without the presence of the interferers near the relay. Numerical results are provided to validate our assumptions.
