Orthogonal One Twenty Phase Sequence Sets Design Using MGA

Abstract

Multi Input and Multi Output (MIMO) radar system and spread spectrum communication system can fundamentally improve the system performance by using a group of specially designed orthogonal signals. In this paper One twenty Phase sequence sets are synthesized using Modified Genetic Algorithm (MGA). MGA is used as a statistical technique for obtaining approximate solutions to combinatorial optimization problems. Some of the synthesized results are presented, and their properties are better than   four-phase sequence sets   known in the literature.  The synthesized One twenty Phase sequence sets are promising for practical application to multiple Radar system and spread spectrum communication. The synthesized sequences also have complex signal structure which is difficult to detect and analyze by enemy electronics support measure. The convergence rate of the algorithm is shown to be good.
