基于模拟退火算法的WCDMA网络天线优化

On the 3G network operation processing, because of the number of users increasing, traffic types of diversification and the surrounding environment changing, the network need to be continuously optimized, so that the network can be in the best condition all the time. This paper generalizes the base station antennas of WCDMA network, mainly studies the antenna gain characteristics, analyses the advantages of antenna optimization with a kind of heuristic algorithm, the simulated annealing algorithm, using network coverage ratio as the cost function, through simulation in the WCDMA network to realize optimization purposes. In the final, analyse the optimization results, compare the optimization effect of the network, summarize the performance of antenna optimization on the network optimization WCDMA .
