Abstract:
1. A method of receiving data in a multiple-input multiple-output (MIMO) communication system, comprising: obtaining an effective channel response matrix for an effective MIMO channel observed by data symbols sent by a transmitting entity, wherein the system supports a plurality of operating modes, each operating mode being associated with different spatial processing on the data symbols by the transmitting entity, and wherein the effective MIMO channel includes a MIMO channel used for data transmission and the spatial processing, if any, performed by the transmitting entity on the data symbols; deriving a spatial filter matrix based on the effective channel response matrix and in accordance with a minimum mean square error (MMSE) technique; and performing spatial processing on symbols received via the MIMO channel with the spatial filter matrix to obtain estimates of the data symbols sent by the transmitting entity.
