Abstract
A method for processing signals in a multi-antenna CDMA radio communication system extracts control signals by despreading signals transmitted to a specific user through the antennas using a spreading factor, estimating weight values of respective ones of the antennas using at least one signal separated from the extracted control signals, and extracting data signals by despreading remaining signals, except for the control signals, using control information provided from control channels. The method then multiplies the extracted data signals by the weight values of the respective antennas, and combines and outputs the data signals multiplied by the weight values.
