Abstract

The invention belongs to the technical field of wireless communication, and discloses a channel characteristic analysis method and system, a medium, equipment and a processing terminal.The channel characteristic analysis method comprises the steps that a deterministic channel model is constructed based on geometric information and electromagnetic information of a specific propagation environment, and a channel characteristic analysis result is obtained by solving a Maxwell equation or an approximate propagation equation; calculating a multi-dimensional channel parameter at the predicted receiving point; proposing a wireless channel characteristic analysis method based on a simulation result of the deterministic channel model; aiming at a propagation scene, systematized and planned parameter extraction and characteristic analysis are carried out on typical channel parameters; on the basis of a K-means algorithm, a multipath parameter is added as a weight measurement, selection of a centroid is optimized, and a channel clustering algorithm is improved. Based on a reverse ray tracing algorithm, accurate electromagnetic wave path prediction and multi-dimensional channel parameter calculation are carried out, a channel characteristic analysis method of the system is defined, and an accurate theoretical basis is provided for wireless communication system design and network planning.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a channel characteristic analysis method, system, medium, equipment and processing terminal. Background technique [0002] At present, the rapid innovation of wireless communication technology in the past two decades has affected the whole world. Whether it is from the vigorous development of science and technology, or from the social impact of industrial transformation and market popularization, its development and popularization have changed people's lives. Way. Wireless communication is different from wired communication through cables, optical fibers and other media. Electromagnetic waves propagate in wireless channels in free space, so the performance of wireless communication is affected by its actual propagation environment. Therefore, in the design of wireless communication systems and During network planning, accurate knowledge of channel char...
