Abstract
Data values are encoded for transmission to a recipient on a communication channel. Performance information associated with the encoding or the communication channel is obtained and used at least in part to determine quantization factors used in the encoding. The data values can be scaled based on the quantization factors and ordered based on a probability factor. A portion of the data values can be selected based on content. A code table can be selected based on a variation of the data values, where the code table specifies codewords including at least one of bits representative of a divisor, bits representative of a remainder, and a bit representative of a sign. Codewords can be generated for the data values using the code table. The encoded data values can be transmitted to a recipient where the data values are decoded using a decoder.
