Abstract :
We consider the transmission of correlated Gaussian sources over orthogonal Gaussian channels. It is shown that the amplify and forward (AF) scheme which simplifies the design of encoders and the decoder, performs close to the optimal scheme even at high SNR. Also, it outperforms a recently proposed scalar quantizer scheme both in performance and complexity. We also study AF when there is side information at the encoders and decoder.
