A method and apparatus for estimating a communication channel (14) in a wireless communication system (10) having multiple transmitter antennas (12) using reduced rank estimation. The method exploits redundant and/or a priori knowledge within a system to simplify the estimation calculations. Ine one embodiment, a covariance matrix is calculated (44) and analyzed (46) to determine if the channel parameters maybe reduced for channel estimation. If not, all parameters are used (50), otherwise a reduced rank matrix (54) is used for the calculation.
