LOW PAR ZERO AUTO-CORRELATION ZONE SEQUENCES FOR CODE SEQUENCE MODULATION

摘要

In one non-limiting exemplary embodiment, a method includes: randomly selecting a set of sequences with each sequence havingsequence elements, each sequence element having a frequency selected from constellation points on a unit circle in a complex plane, where the selected set of sequences isa candidate set of sequences; calculating a first cubic metric and a second cubic metric for each sequence of the candidate set of sequences, where the first cubic metric is for single code modulation and the second cubic metric is for multicode modulation; and in response to the first cubic metric and the second cubic metric being larger than at least one threshold, removing the corresponding sequence from the candidate set of sequences to obtain at least one saved sequence..
