Abstract
AbstractIn this paper, we derive the exact symbol error probability (SEP) of cooperative systems using amplify and forward (AF) relaying and partial relay selection when the different links are independent and non‐identically distributed. In conventional relay selection, the selected relay offers the best instantaneous signal to noise ratio (SNR) of the relaying link (source‐relay‐destination). However, partial relay selection uses only the SNR of the source to relays links. The exact expression of the moment generating function (MGF) of the SNR at the destination is also derived.
