Bit-Error Rate Analysis of Relay-Based DF Cooperative Diversity Systems Considering Multipath Fading Channels Along with Non-Identical Interferers

Incremental relaying, as a form of adaptive relaying, was introduced to compensate for the limitations of fixed relaying schemes which attributed to the improper channel utilization bearing in mind that the relay nodes forwards the sources' signal to the destination in a predetermined manner without taking into considerations the channel conditions between the source-destination links. In this article, a study of a two-hop decode-and-forward cooperative incremental relaying performance considering the existence of L interfering signals nearby the destination over different types of fading channels is presented. Interestingly, a mathematical bit error rate derivation is exhibited and ultimately plotted.
