Abstract

Disclosed are a double-stream beamforming method and device, which relate to communication technology. The method comprises: first, according to a DOA angle, determining an array response vector; then according to the array response vector, in accordance with the number of each group of transmission antennae of a base station, distributing parameters to generate two groups of coefficients, and according to the two groups of coefficients, conducting beamforming on the antennae. There is no need to conduct characteristic value decomposition to obtain a characteristic vector, thereby reducing the double-stream beamforming complexity.
