Title:
WEIGHTED I1-NORM SPARSE CONSTRAINT ROBUST BEAMFORMING METHOD AND DEVICE UNDER IMPULSE NOISE
Document Type and Number:
WIPO Patent Application WO/2018/165971
Kind Code:
A1
Abstract:
A weighted i1-norm sparse constraint robust beamforming method and device under impulse noise, applicable to the technical field of communications. The method comprises: establishing an optimization formula according to a statistical average of absolute values of array outputs and the sparsity of a beam pattern (S101); constructing a weighting matrix by means of infinity-norm normalization and an eigen-subspace method (S102); and calculating an optimal weight vector based on an iterative reweighted least squares method, and calculating a signal-to-interference-plus-noise ratio according to the optimal weight vector (S103). Compared with the prior art, by means of the method, large constraints are adaptively applied to interference signals, thereby significantly improving an interference suppression capability, and increasing an output signal-to-interference-plus-noise ratio.
