Null-steering beamformer — Null Steering is a method of beam forming for narrow band signals where we want to have a simple way of compensating delays of receiving signals from a specific source at different elements of the antenna array. In general to make use of the… … Wikipedia
Phased array — This article is about general theory and electromagnetic phased array. For the ultrasonic and medical imaging application, see phased array ultrasonics. In wave theory, a phased array is a group of antennas in which the relative phases of the… … Wikipedia
антенная решетка с управляемым положением нуля — Тип антенной решетки, в диаграмме направленности которой формируется узкий провал в направлении на источник помех. Управление положением нуля диаграммы направленности осуществляется таким образом, чтобы сигнал помехи был практически подавлен.… … Справочник технического переводчика
Beamforming — is a signal processing technique used in sensor arrays for directional signal transmission or reception. This spatial selectivity is achieved by using adaptive or fixed receive/transmit beampattern. The improvement compared with an… … Wikipedia
Zero-forcing precoding — Zero forcing (or Null Steering) precoding is a spatial signal processing by which the multiple antenna transmitter can null multiuser interference signals in wireless communications. Regularized zero forcing precoding is enhanced processing to… … Wikipedia
Degrees of freedom (mechanics) — In mechanics, degrees of freedom (DOF) are the set of independent displacements and/or rotations that specify completely the displaced or deformed position and orientation of the body or system. This is a fundamental concept relating to systems… … Wikipedia
