Source coding with feedforward: Gaussian sources

Abstract

This paper describes the source coding of the information signals with feedforward Gaussian sources. A stationary memoryless Gaussian source with zero-mean and variance, and with mean squared error as the distortion measure, gives a deterministic scheme that achieves the optimal rate-distortion bound using simple uniform scalar quantizers. To reconstruct source codes, the decoder uses the optimal Shannon rate-distortion function and achieves channel coding with feedback.
