METHODS, APPARATUS AND SYSTEMS USING A MULTIDIMENSIONAL GRAY CODING SCHEME FOR REAL NUMBER M-ARY QAM SIGNALING

摘要

Methods, apparatus and systems using a multidimensional gray coding scheme for real number M-ary QAM signaling is disclosed. One representative method of data encoding includes segmenting a bit stream of binary data into sets; mapping the segmented sets of binary data to signal vectors of a multidimensional real number M-ary constellation; and generating M-ary signal elements corresponding to the mapped set of binary data based on the signal vectors of the multidimensional real number M-ary constellation.
