Problems solved by technology

The optimization method of the antenna feeder parameters in the TD-SCDMA network provided in the prior art only involves the optimization of a single antenna feeder parameter each time, and cannot jointly optimize multiple antenna feeder parameters, resulting in low work efficiency, and after the antenna feeder parameters are optimized, It is necessary to repeatedly evaluate the road test to achieve the optimization goal, and the workload is huge; the optimization scheme of the antenna feeder parameters formulated manually has problems of subjectivity and one-sidedness, and the adjustment range of the antenna feeder parameters is limited, so it is difficult to achieve wireless network optimization. The overall performance is optimal, making it difficult to guarantee the quality of the wireless network
