METHODS AND APPARATUS FOR COMMUNICATIONS WITH FINITE BLOCKLENGTH CODED MODULATION

摘要

A method includes obtaining a capacity gap and a dispersion scaling factor of the channel, the capacity gap being a difference between a theoretical capacity of the channel and a corrected capacity of the channel, and the dispersion scaling factor being a square root of a ratio of a corrected dispersion of the channel to a theoretical dispersion of the channel; estimating a channel capacity and a channel dispersion for the channel in accordance with the capacity gap, the dispersion scaling factor, a channel quality of the channel, and a modulation level of the channel; and determining a performance characteristic of the channel in accordance with the channel capacity of the channel, the channel dispersion of the channel, and a blocklength of a code used for transmissions over the channel.
