Abstract:
1. A method for communications, comprising: grouping, with circuitry, a set of samples into a block; determining, with the circuitry, at least one scaling factor for the set of samples in the block, the scaling factor being indicative of a number of redundant signs bits that can be removed from each sample in the block; determining, by the circuitry, whether a unique scaling factor exists among the samples in the block; scaling, with the circuitry, sign extension bits from the set of samples in the block using the scaling factor to provide a set of scaled samples in the block; quantizing, with the circuitry, the set of scaled samples in the block to provide a set of quantized samples in the block; and encoding, with the circuitry, a scaling code word for the block based on a number of sign extension bits scaled from the samples in the block and whether the unique scaling factor exists.
