Possible choices are: an i.i.d. Gaussian codebook, a codebook drawn uniformly over a sphere, as well as a codebook drawn uniformly over the Voronoi region of a lattice that is “good for quantization” (see [7]). WebGaussian codebook and white Gaussian noise constitute a unique saddle point. In [11], [12] (and references therein) it was shown that a Gaussian codebook and minimum Euclidean distance decoding achieves rate 1 2 log(1 + P=N 0) under an average power constraint.

WebThe listsize capacity is computed for the Gaussian channel with a helper that—cognizant of the channel-noise sequence but not of the transmitted message—provides the decoder with a rate-limited description of said sequence. This capacity is shown to equal the sum of the cutoff rate of the Gaussian channel without … WebIt is shown that the use of a Gaussian codebook to compress any ergodic source results in an average distortion which depends on the source via its second moment only. The source with a given second moment that is most difficult to describe is the memoryless zero-mean Gaussian source, and it is best described using a Gaussian codebook.
