Problems solved by technology

But these two algorithms have their own limitations: the non-blind estimation algorithm needs reference signals, such as training sequences or pilots, that is, the receiving end knows the reference signals in advance, and then determines the value of each array element according to the received results. Channel response, which determines the channel matrix of the antenna array and the direction of arrival of the signal, and then uses the algorithm to adaptively adjust the weighted value according to certain criteria
Although the blind estimation algorithm does not waste the signal bandwidth, its error is large, the convergence speed is slow, and it is easy to miscalculate the small extreme points, especially in the fast time-varying channel environment, the effect is not ideal

Abstract

The invention provides a beam forming-optimizing method and device. A base station acquires current position property information of an accessed mobile terminal, and performs beam forming under the assistance of the current position property information of the mobile terminal. The base station determines a general direction of a signal incoming wave according to the current position of the mobile terminal, so that a scanning range of a beam direction is reduced; the convergence domain of the beam forming is reduced; and the aim of accelerating the convergence speed of the beam forming is fulfilled.

Description

technical field [0001] The invention belongs to the technical field of antennas, and in particular relates to a beamforming optimization method and device. Background technique [0002] Beamforming is the combination of antenna technology and digital signal processing technology for directional signal transmission or reception. Beamforming uses an array antenna. An array antenna is an antenna system composed of many identical individual antennas (for example, symmetrical antennas) arranged in a certain order, also known as an antenna array. The independent units of the antenna array are called array elements or antenna units. After properly weighting the input and output of each array element in the array antenna, the antenna array can generate directional beams in one or more specific directions in space, that is, the pattern of the antenna array can be changed, and its directivity can be controlled , so as to effectively track useful signals and suppress interference and ...
