Abstract

The invention discloses a channel prediction method based on a matrix bundle, which considers the actual problem of multipath time delay change caused by user side movement, and obtains the rule of time delay change by constructing a three-dimensional matrix bundle and estimating time delays at different moments aiming at the time-varying characteristic of a channel, especially the influence of the time delay change on the channel. According to the method, a multi-path azimuth angle, a pitch angle, time-varying delay and Doppler parameters are respectively estimated based on a matrix pencil super-resolution method, and a channel is reconstructed based on the estimated channel parameters, so that the adverse effect of outdated channel state information (CSI) on communication can be effectively overcome, and accurate prediction of a future time-varying channel is realized.

Description

technical field [0001] The present invention belongs to the field of wireless communication, and more particularly, relates to a channel prediction method based on matrix beams. Background technique [0002] In recent years, mobile communication technology has developed rapidly. Compared with 4G, 5G mobile communication system has higher spectral efficiency and peak rate, can meet the data transmission needs of a large number of end users, and can achieve high-speed, high-reliability, and low-latency information transmission. One of the key technologies of 5G is massive multiple-input multiple-output (massive MIMO) technology. Compared with the traditional MIMO technology, massive MIMO is configured with more antenna panels and antenna arrays at the base station (BS), which can fully exploit the freedom of space and has significant advantages, such as: improving the capacity of wireless communication systems , data transfer rate, spectral efficiency and energy efficiency. ...
