Abstract

Embodiments of the invention provide a channel tracking method and device, and relates to the field of communication channel processing. The method and system can perform channel tracking on communication systems provided with uniform rectangular arrays. The method includes obtaining an initial emission horizontal angle, an initial emission pitch angle, an initial receiving horizontal angle, an initial receiving pitch angle and preset gain information; calculating the desired value of a channel matrix of a current time block on the basis of a preset channel matrix formula and channel time-varying formula according to the obtained information; calculating the estimated values of a horizontal and vertical array of the current time block according to the obtained information, a preset angle time-varying formula and the preset channel matrix formula; obtaining the optimal value of the horizontal and vertical array of the current time block on the basis of a matrix decomposition algorithm according to the estimated values of the horizontal and vertical array of the current time block and the desired value of the channel matrix of the current time block; and calculating the optimal valueof the channel matrix of the current time block according to the optimal value of the horizontal and vertical array of the current time block.

Description

technical field [0001] The invention relates to the field of communication channel processing, in particular to a channel tracking method and device. Background technique [0002] With the vigorous development of global wireless communication technology and Internet technology, the number of mobile users has shown explosive growth, and various new mobile services have emerged continuously. The future 5G mobile communication system needs to support not only voice functions, but also digital, image, multimedia and other data transmissions. Compared with 4G in terms of transmission efficiency and coverage, it must be one or more orders of magnitude higher than that of 4G to meet the 1000-fold increase in mobile Internet traffic within 10 years. development needs. The millimeter wave frequency band (30–300GHz) has abundant spectrum resources. The combination of millimeter wave and massive multiple input multiple output (MIMO) can bring huge spatial gain, energy efficiency and s...
