ABSTRACT - We investigate the Gaussian side information channel. First we derive a lower and an upper bound for its capacity. Then we discuss two techniques that yield rates that improve upon the lower bound. The first technique compensates part of the disturbing noise, the second concentrates the disturbing noise on a set of values. Although both techniques perform reasonably, the capacity still remains to be determined.

ABSTRACT - We investigate the Gaussian side information channel in the Shannon [1958] setup.and propose a method that achieves correlation between the signal and the side information noise. The capacity still remains to be determined however.
