Abstract
- This current paper addresses the noncooperative distributed wireless relay networks under a jamming environment. The amplify- and-forward single-input multiple-output (SIMO) and multiple-input single-output (MISO) schemes are considered with multiple N-relay nodes. The main contribution of this paper is to determine the optimal relay precoder vectors by minimizing the minimum mean square error (MSE) criterion. Using the derived optimal relay precoder vectors, the impacts on the jamming environment in the AF SIMO/MISO wireless relay systems are investigated using bit error rate (BER). Results show that the diversity order of a system decreases under a jamming environment. It is also seen that the system BER performance enhances as the number of relay nodes N increases.
