Under conditions of low sample support, a low-rank solution of the Minimum Variance Distortionless Response (MVDR) equations can yield a higher output SINR than the full-rank MVDR beamformer. In this thesis, several low-rank beamform- ing techniques
介绍了什么是波束形成；以及波束形成各种基本知识及原理，介绍了阵列理论； Beamforming is a signal processing technique used in arrays for directional signal transmission or reception.This is achieved by combining elements in the array in away where signals at particular angles experienc
Abstract—A random beamforming (RBF) technique is proposed to achieve omnidirectional coverage for broadcast channels in multipleantenna systems. In the proposed scheme, the time and frequency resources for communication are divided into many time–fr
