Abstract :
This paper presents a non cooperative distributed minimum mean square error (MMSE) relay scheme. It is designed for wireless relay networks based on an amplify and forward (AF) strategy for one-source, one-destination pair and N relay nodes. Both broadband noise jamming and channel uncertainty were studied in a wireless relay network under received power constraint. The main contribution of this paper is the derivation of the MMSE-based diagonal relay amplifying matrix in wireless relay networks under both broadband jamming and channel uncertainty. Effects of jamming and channel uncertainty using the derived diagonal relay amplifying matrix were evaluated. Bit error rate (BER) performance was investigated using Monte-Carlo simulations.
