On Joint Source-Channel Coding for the Non-White Gaussian Case

Abstract

The paper presents performance limits for transmitting correlated Gaussian signals over additive, Gaussian channels with memory and limited transmit power. Both absolute performance limits as well as performance limits for linear systems are given. A bandwidth matching technique is introduced for the adaptation of the signal to the channel. This can be used as an instrument for resource allocation when combining subband source decomposition and OFDM transmission in a source-channel coding environment
