Abstract

This application provides a channel type identification method, apparatus, electronic device, and storage medium, which can solve the technical problem of poor channel type identification performance in related technologies. The method includes: measuring a reference signal to determine the channel characteristics of the channel corresponding to the reference signal; determining the channel type based on the channel characteristics; and the channel type being correlated with the number of dominant paths in the channel. Since the transmit power, modulation format, frame structure, and other parameters of the reference signal are known information at the receiver, the superposition effects of non-inherent features such as noise and interference can be effectively filtered out, and the extracted channel features can accurately map the channel type. This eliminates the high-order computational steps of spectrum estimation, significantly reducing the processor's computational load and memory usage, adapting to the application needs of low-to-medium computing power terminal devices, and ensuring the stability and reliability of the channel type determination results by avoiding interference from non-inherent features.
