Abstract

The embodiment of the invention provides a collected data-based wireless channel transmission model establishing method and system. The method mainly comprises collecting the channel information of a tested region through an information collecting system, which comprises a geographic information system; performing wireless channel analysis on the channel information of the tested region through a distributed computation system to obtain the wireless channel transmission model of the tested region; according to the wireless channel transmission model of the tested region, structuring the correlation between the geological information of the tested region and wireless channel characteristic information. The collected data-based wireless channel transmission model establishing method helps obtain the wireless channel transmission model by mining mass data, performing wireless channel analysis on the mass channel correlated information through the distributed computation system and analyzing the correlation of the mass channel correlated information, thereby improving the accuracy of the wireless channel transmission model and wireless channel prediction.

Description

technical field [0001] The invention relates to the technical field of wireless channel models, in particular to a method and system for establishing a wireless channel propagation model based on collected data. Background technique [0002] Any communication system, the channel is an essential component. The wireless channel is a typical "variable parameter channel". The characteristics of the wireless channel are closely related to the propagation environment-terrain, ground objects, climate characteristics, electromagnetic interference, the moving speed of the communication object and the frequency band used. The communication capability and QoS (Quality of Service) of the wireless communication system, and the wireless transmission technology to be adopted by the wireless communication equipment are closely related to the performance of the wireless channel. Therefore, in order to transmit useful information with high quality and large capacity as possible on limited sp...
