Abstract :
This paper describes cell density and effective channel code rates for quantizers with uniform decoders and channel-optimized encoders. In particular, the natural binary code index assignment is investigated which is called as modified natural code. The occurrences of empty encoding cells in such quantizers compute their effective channel code rate. Also the high-resolution distributions of the encoding cells are examined and the mean squared errors the quantizers achieve.
