Abstract :
The main contribution of this paper is the derivation of an optimal diagonal amplifying relay matrix. This matrix is for a non cooperative distributed wireless relay network in a jamming environment. Minimum mean square error (MMSE) criterion was used in this study. Jamming location was also studied in this paper. Results show that diversity of a system can be degraded or even get lost depending on jamming location. A single-input multiple-output (SIMO) system strategy was implemented, using one-source, M-destination and N-relay nodes. System performance for the new derived matrix was evaluated using bit error rate (BER). Also, performance comparisons with/without jamming were a focus in our study.
