Linear transceiver design for an amplify-and-forward relay based on the MBER criterion
Linear transceiver design for an amplify-and-forward relay based on the MBER criterion
A design methodology based on the Minimum Bit Error Ratio (MBER) framework is proposed for a nonregenerative Multiple-Input Multiple-Output (MIMO) relayaided system to determine various linear parameters. We consider both the Relay-Destination (RD) as well as the Source- Relay-Destination (SRD) link design based on this MBER framework, including the precoder, the Amplify-and-Forward (AF) matrix and the equalizer matrix of our system. It has been shown in the previous literature that MBER based communication systems are capable of reducing the Bit-Error- Ratio (BER) compared to their Linear Minimum Mean Square Error (LMMSE) based counterparts. We design a novel relay aided system using various signal constellations, ranging from QPSK to the general M-QAM and M-PSK constellations. Finally, we propose its sub-optimal versions for reducing the computational complexity imposed. Our simulation results demonstrate that the proposed scheme indeed achieves a significant BER reduction over the existing LMMSE scheme

Abstract
A design methodology based on the Minimum Bit Error Ratio (MBER) framework is proposed for a nonregenerative Multiple-Input Multiple-Output (MIMO) relayaided system to determine various linear parameters. We consider both the Relay-Destination (RD) as well as the Source- Relay-Destination (SRD) link design based on this MBER framework, including the precoder, the Amplify-and-Forward (AF) matrix and the equalizer matrix of our system. It has been shown in the previous literature that MBER based communication systems are capable of reducing the Bit-Error- Ratio (BER) compared to their Linear Minimum Mean Square Error (LMMSE) based counterparts. We design a novel relay aided system using various signal constellations, ranging from QPSK to the general M-QAM and M-PSK constellations. Finally, we propose its sub-optimal versions for reducing the computational complexity imposed. Our simulation results demonstrate that the proposed scheme indeed achieves a significant BER reduction over the existing LMMSE scheme
