MULTI-BIT CODE MODULATION MAPPING METHOD, DEVICE AND COMPUTER STORAGE MEDIUM

摘要

Disclosed is a multi-element code modulation mapping method and device, relating to communications and designed to improve communication reliability. The method includes that: multi-element domain coding is performed on a first sequence including K multi-element codes to obtain a second sequence including N multi-element codes; K 1 and K 2 are calculated according to a multi-element domain element number q and a modulation order M, wherein K 1 * log 2 q = K 2 *log 2 M, both K 1 and K 2 are integers not smaller than 2, and both q and M are power of 2; the second sequence is divided into z groups of multi-element codes with each group including K 1 multi-element codes, wherein C=formula (I), and formula (II) represents rounding up; each group of multi-element codes is mapped to a constellation diagram to form K 2 Mth-order modulation symbols; and z groups of Mth-order modulation symbols are sequentially cascaded to form a modulation symbol to be sent. The present disclosure further discloses a computer storage medium.
