Research of Ecologic System Optimization Algorithms for Multi-user Detection in CDMA Communication Systems

Xu Yao-hua Hu Yan-jun (School of Electronic Science and Technology, Anhui University, Hefei, 230039, China)  
An ecologic system optimization algorithm is a type of new developed evolutionary algorithm, which is based on swarm intelligence, and has the properties of converge quickly, simple rules. This paper research the ant colony optimization algorithm and the particle swarm optimization on discrete space, and describe two algorithms for the multi-user detection problem in Code Division Multiple Access(CDMA) communication system.The approach using some new methods to improve the search quality and efficiency, analyses and simulation results show the approach has low computational complexity, and the BER property of the algorithm is better than the conventional detector, to find a new method to solve the problem of MUD in CDMA.
