AI Technical Summary

Problems solved by technology

This method has high professional requirements for planners. If planners are inexperienced, it will lead to wrong selection of wireless propagation model, which will affect the final planning result. Therefore, the selection accuracy of wireless propagation model is too low.
Moreover, this manual method lacks a uniform standard among planners, resulting in that the consistency of selection results cannot be guaranteed
Also, the selection efficiency of this manual method is too low

Abstract

The invention discloses a method for automatic selection of wireless transmission modes, which comprises: (a) setting up a wireless transmission mode databank storing the known wireless transmission modes therein; (b) determining transmission environment characteristic parameters Ai of the known wireless transmission modes in the wireless transmission mode databank, wherein i is the labeling number of the known wireless transmission mode; (c) determining a transmission environment characteristic parameter B of a target zone; (d) determining a difference value between B and each Ai determined in the step (b), selecting the minimal difference value to compare with a threshold value, if the minimal difference value is smaller than the threshold value, selecting the wireless transmission mode, in correspondence to the minimal difference value, as the wireless transmission mode of the target zone. The invention can increase the accuracy and efficiency of the selection of the wireless transmission modes and ensure the consistency of selection results.

Description

technical field [0001] The invention relates to cellular wireless communication technology, in particular to a method for automatically selecting a wireless propagation model of a wireless communication system. Background technique [0002] The wireless propagation model is an important basis for predicting path loss in wireless communication network planning, and the accuracy of the wireless propagation model has a great influence on the quality of network planning. [0003] When designing a new network topology, it is necessary to predict the coverage radius of each cell, and the wireless propagation model is one of the important factors affecting the prediction accuracy. Therefore, in order to obtain a satisfactory planning effect, it is first necessary to obtain a wireless propagation model that conforms to the propagation characteristics of the target area. [0004] At present, there are two methods to obtain a wireless propagation model that conforms to the propagatio...
