Patent ID: 8675772

Claim:
A method of generating signals for transmitting from at least two antennae of a wireless communications system comprising the steps of: determining a channel correlation coefficient (ρ) from signals received on a reverse link, wherein the channel correlation coefficient is an estimate of an auto-correlation coefficient of channel gain from an antenna evaluated at a specified time delay; using the channel correlation coefficient (ρ) to select a code correlation parameter (λ) wherein the code correlation parameter (λ) determines the correlation of the encoded signals to said at least two antennae; feeding a signal representative of a beamforming weight parameter to an encoder to modify a stream of information symbols; feeding the code correlation parameter (λ) to the encoder to control the proportion of orthogonal coding relative to beamforming of the stream of information symbols that are to be transmitted; and feeding the stream of information symbols modified by the code correlation parameter to said at least two antennae for transmission.
