Abstract
A method is provided. The method includes computing a beamforming weight matrix W; and using the beamforming weight matrix W to transmit and/or receive data. The beamforming matrix W is computed from a weighted channel estimate matrix Formulae (A): and a channel estimation error matrix Formulae (B): the weighted channel estimate matrix Formulae (C): satisfying a condition, and where Ĥ is a channel estimate matrix and ρ is a weighting factor matrix and ∘ denotes a matrix operation. The weighting factor matrix ρ is such that zeroes of the rows or columns of the weighted channel estimate matrix Formulae (C): are moved as compared to zeroes of the rows or columns of the channel estimate matrix Ĥ.
