Abstract :
We derive the optimal rate allocation of the shape and gain components of a certain shape-gain quantizer for a Gaussian source. The rate allocation results are of particular interest because the shape-gain quantizer addressed in this paper is the best vector quantizer known for the memoryless Gaussian source at rates of three or higher
