Cooperative Distributed MISO Wireless Relay Networks Under Jamming Environments with Power Constraints

This paper introduces a cooperative distributed wireless relay network under a jamming environment at three different locations. An amplify-and-forward (AF) multiple-input single-output (MISO) system is considered with N-relay nodes. For full relay cooperation, all relay nodes in wireless relay networks exchange their received signals from source nodes with no errors. An optimal non-diagonal amplifying relay matrix is derived using the minimum mean square error (MMSE) criterion under power constraints at the relay nodes. The performance of the system by implementing the derived optimal non-diagonal amplifying relay matrix is evaluated using the bit error rate (BER). For performance comparison, no-jamming environment and the other three special cases corresponding to different locations of the broadband noise jamming (BNJ) are also considered.
