Abstract
The present invention provides a method of transforming pre-coded signals for transmission over an air interface in a MIMO wireless communication system. Embodiments of the method may include applying, at a transmitter, a transform matrix and a pre-coding matrix to a signal prior to transmitting the signal using a plurality of antennas deployed in a first antenna configuration. The pre-coding matrix is selected from a codebook defined for a second antenna configuration deployed in a non-scattering environment. The transform matrix is defined based on the first antenna configuration and a scattering environment associated with the transmitter.
