A design methodology based on the minimum error probability (MEP) framework is proposed for a nonregenerative multiple-input multiple-output relay-aided system. We consider the associated cognitive, the parallel, and the multihop source-relay-destination link design based on this MEP framework, including the transmit precoder, the amplify-and-forward relay matrix, and the receiver equalizer matrix of our system. It has been shown in the literature that MEP-based communication systems are capable of improving the error probability of other linear counterparts. Our simulation results demonstrate that the proposed scheme indeed achieves a significant bit-error-ratio reduction over the existing linear schemes.
