Channel modeling method and device, electronic equipment and storage medium

Abstract

The invention provides a channel modeling method and device, electronic equipment and a storage medium. The method comprises the following steps: determining the positions of a transmitting end Tx, a receiving end Rx and at least one anti-scatterer; determining respective signal models of the at least two signals of the target channel based on the Tx, the Rx and the position of the at least one backscatterer; wherein different types of signals correspond to different cluster structures, and each cluster structure comprises at least one of the following items: a direct reflection cluster LOSC, a static reflection cluster SC, a mobile reflection cluster MC and a mirror image cluster TC. According to the method, channel modeling is carried out on various signals of the target channel based on the geometric position relation of the Tx, the Rx and the backscatterer, and different types of signals correspond to different cluster structures, so that the irregular random geometric mixed channel model based on the cluster structures is effectively realized, the accuracy of the model is improved, the expansibility is high, and the method is suitable for popularization and application. Therefore, the universality of the model is improved, and repeated measurement of the channel is avoided.
