Abstract

In this paper a novel Modified Simulated Annealing Algorithm (MSAA) is used as global optimization technique to find the solution of combinatorial optimization problem which is usually difficult to tackle. MSAA combines good methodologies like global minimum converging property of Simulated Annealing algorithm and fast convergence rate of Hamming scan algorithm. Orthogonal Netted Radar System (ONRS) and spread spectrum communication system can fundamentally improve the system performance by using a group of specially designed orthogonal signals. MSAA is used to synthesize orthogonal eight-phase sequence sets with good autocorrelation and cross correlation properties. Some of the synthesized sequence sets are presented, and their properties are better than four-phase sequence sets known in the literature. The synthesized eight-phase sequence sets are promising for practical application to Netted Radar System and spread spectrum communication. The effect of Doppler shift on synthesized sequences set is also investigated using ambiguity function. The convergence rate of the algorithm is shown to be good.
