Optimization for location of TD-SCDMA base stations based on immune algorithm

Aiming at the shortcomings of the available methods for 3G base stations and the characteristics of TD-SCDMA,a new method is proposed based on immune algorithm for site selection.The mathematical model and the realization are given.The algorithm has following characters:the maximum number of base stations is given with the need for the coverage and capacity,so it effectively reduces the cost;antibody coding uses the base station coordinates for engineering applications.Further more,an information entropy selection based on antibody concentration is used to prevent premature convergence of the algorithm.Simulation results show that the algorithm can effectively find base station layouts which can lower the price and get higher coverage and capacity.
