Patent number: 9998251Abstract: Embodiments herein achieve a method and system for selecting non-coherent spreading sequences with binary alphabets {0, 1} with variable spreading factors. The method generates circular shift equivalent sets of spreading sequences by circularly shifting base sequences with elements {1, 0} and having at least one variable spreading factor. The method determines whether each spreading sequence in the circular shift equivalent set meets pre-defined spreading sequence criteria. The spreading sequence criteria comprise balanced criteria, a non- repetition criteria, non-circular criteria, and conjugate criteria. Furthermore, the method selects the spreading sequence from expansions of at least one spreading sequence from the circular shift equivalent sets in response to determining that the spreading sequences in the circular shift equivalent sets meets the pre-defined spreading sequence criteria.Type: GrantFiled: October 22, 2014Date of Patent: June 12, 2018Assignee: Samsung Electronics Co., Ltd.Inventors: Jinesh Parameshwaran Nair, Young Jun Hong, Chang Soon Park, Sujit Jos, Young Soo Kim, Manoj Choudhary
