Abstract

The invention provides a channel estimation method and device, electronic equipment and a storage medium, and the method comprises the steps: determining an angle set corresponding to a channel path in a pilot signal and an initial sensing matrix; calculating an inner product absolute value of each column of the initial sensing matrix and a signal residual error to obtain an angle set initial index; performing mesh refinement on a target angle range corresponding to the angle set initial index to obtain an angle set offset index; iteratively updating the angle set based on the angle set bias index to obtain a global sensing matrix and a new angle set; subtracting the influence of all paths except the current path to be updated from the pilot signal, and iterating again; and based on the target global perception matrix array and the target angle set, calculating to obtain a path gain and an original channel. According to the invention, the defect of millimeter wave channel power leakage in the prior art can be solved, mutual interference between channel paths is reduced, and the accuracy of channel path angle estimation is improved.

Description

technical field [0001] The present invention relates to the field of information technology, and in particular, to a channel estimation method, apparatus, electronic device and storage medium. Background technique [0002] In the era of fifth-generation mobile communications (5G, Fifth Generation), emerging applications such as the Internet of Vehicles, Internet of Things, virtual reality, and smart cities are developing rapidly, and the demand for high data rates, capacity, and spectral efficiency has surged. However, due to the sub-6GHz frequency band The available spectrum of China is constantly crowded and scarce, while the available resources of the millimeter-wave band are abundant, and there is a large bandwidth that can support gigabit data rates. Therefore, millimeter-wave occupies an important position in 5G communication. [0003] In view of the sparse characteristics of mmWave channels, compressed sensing technology has been widely studied and applied in mmWave c...
