Abstract

The invention discloses an electromagnetic wave transmission forecast method and device. The electromagnetic wave transmission forecast method and device aim to solve the problem that an existing ray tracing method is low in computational efficiency. The method comprises the steps of constructing a kd tree according to a scene space with a plurality of surface elements; tracing electromagnetic wave rays from a transmitting point by transmitting bounced rays, traversing the constructed kd tree in the tracing process to quicken searching of the effective surface element intersecting with the electromagnetic wave rays, and obtaining all possible propagation paths of the electromagnetic wave rays within the set mutual threshold value of reflecting and transmitting; judging all the possible paths through the image method, and finding the legal paths capable of reaching a receiving point from the transmitting point; and calculating the signal strength generated when the electromagnetic wave rays of each legal path reach the receiving point.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to an electromagnetic wave propagation prediction method and device. Background technique [0002] In the existing communication technology, in order to improve indoor wireless signal coverage, the most economical and quickest method is to install an indoor signal transmitter. In order to achieve usable signal strength in various indoor places, to improve communication quality, and to provide users with satisfactory services, it is necessary to quickly and accurately predict the coverage trend of indoor signals, and correctly estimate the reasonable placement of indoor signal transmitters. [0003] Indoor wireless signal propagation models are mainly divided into empirical models and deterministic models. The deterministic model is also called the fixed-point propagation model. It describes the indoor wireless signal propagation based on the electromagnetic wave propagation...
