TD-SCDMA frequency assignment method

The invention relates to a TD-SCDMA frequency assignment method. Problems in the TD-SCDMA frequency are solved with the hyper-heuristics genetic algorithm. The problems that an existing method is precocious in convergence and long in operation time are solved. The execution process of the hyper-heuristics genetic algorithm is shown in the figure. According to the hyper-heuristics genetic algorithm, an appropriate strategy profile is selected with the high-layer genetic algorithm to continuously optimize annoyance values of a current frequency assignment scheme, and the network quality is continuously improved. According to the TD-SCDMA interference calculation formula, six optimizing strategies are designed and comprise the greedy strategy, the random strategy and the high-speed searching strategy, the random strategy is prevented from being caught into local optimum, and the searching speed can be increased through the high-speed searching strategy. By means of the TD-SCDMA frequency assignment method, the frequency assignment scheme with small interference can be found within a short time.
