Patent ID: 6952459

Claim:
Method for obtaining a transmission gain function for an array of antennae, comprising the steps of: weighting a signal to be transmitted with the array of antennae by a transmission weighting vector {overscore (b)} d with N complex coefficients, wherein N is a number of antennae in the array of antennae; transmitting from the array of antennae to a telecommunication terminal over a downlink channel a downlink transmission signal S d , wherein the downlink channel is disturbed by at least one of an isotropic noise N′ and a downlink interference I d ; transmitting from the telecommunication terminal to the array of antennae over an uplink channel an uplink transmission signal S u ; and determining the transmission weighting vector {overscore (b)} d by a matrix product from a noise power matrix D d , wherein the noise power matrix D d is a function of a power of said isotropic noise N′, a power of said downlink interference I d and a downlink channel vector {overscore (C)} d , said downlink channel vector representing an angular sampling of a transfer function of the downlink channel in M directions k, k=0, . . . , M−1, belonging to an angular range covered by the array of antennae.
