Research On Key Technolgies Of Signal Prediction And Software Implementation In Wireless Network Planning

With the development of wireless communication technolgy,the importance of wireless network planning is also reflected.At the same time,in the wireless network planning,there is a high degree of relevance for the signal prediction model.Many existing standard signal propagation models have their own application scenarios.In this paper,the model of wireless signal propagation is described,and the corresponding software is developed.The following is the specific work of the paper:(1)An effective modeling method for Berg micro cellular propagation model is proposed.In order to meet a certain time consumption and algorithm complexity,the platform of independent research and development in the laboratory has been implemented.(2)In view of the existing platform test data filtering algorithm,joined the road test data is in the algorithm of judging the streets within the range,the data filtering is more in line with the Berg propagation model.(3)Based on the existing planning software,a more optimal correction algorithm,weighted least square method,is adopted to make the model more accurate and more complex and time consuming.(4)Finally,according to the above work,the model is corrected,and compared with the data,which makes the calculation accuracy of the Berg micro cellular communication model to meet the standard of the industry.
