On the role of feedforward in Gaussian sources: Point-to-point source coding and multiple description source coding
Source coding with noiseless feedforward deals with efficient quantization of information sources into indexes, where to reconstruct a source sample, the decoder in addition to this index, has access to all the previous noiseless source samples. This problem may find applications in sensor networks, economics, and control theory. In the first part of this paper, we consider a deterministic block coding scheme for independent and identically distributed (i.i.d.) Gaussian sources. We show that this scheme is asymptotically optimal in terms of its rate-distortion function and the error exponent.
