Abstract
In mobile communications networks, requirements on signal distortion may be fulfilled at a lower bit rate, or alternatively quantization noise be reduced for a given bit rate, by including fractional exponent bits in a block floating point format. One or more fractional exponent bits may apply to all samples in the block. Alternatively, fractional bits may apply to sub-blocks within the block. The optimal number of fractional bits depends on the number of samples in the block.
