Abstract :
A linear relay precoding design scheme is proposed based on distortion channel estimation in the amplify-and-forward MIMO relay system, this scheme modeles the channel estimation errors as Gaussian random variables. The closed-form solution is derived according to the minimum mean squared error (MMSE) criterion. The numerical simulation results show that comparing with other schemes that do not consider channel estimation errors, this scheme achieves better performance in terms of both mean squared error (MSE) and bit error rate (BER).
