We study the zero-delay joint source-channel coding problem of transmitting a Gaussian source over a Gaussian channel in the presence of side information known only to the receiver. To achieve zero-delay, after applying scalar quantization to the source, the properly scaled analog information, namely the quantization error, is superimposed on the scaled digital information, i.e., the quantized source, and then transmitted. At the decoder, two decoding schemes are proposed, both of which… CONTINUE READING
