Abstract:
1. A method for processing signals in a CDMA radio communication system having a plurality of antennas, comprising: extracting control signals by despreading signals transmitted to a specified user through the plurality of antennas using a predetermined spreading factor; estimating weight values of respective ones of the plurality of antennas using at least one signal separated from the extracted control signals; extracting data signals by despreading remaining signals, except for the control signals, among the signals transmitted to the specified user using control information provided from control channels; multiplying the extracted data signals by the weight values of the respective antennas; and combining and outputting the data signals multiplied by the weight values, wherein estimating the weight values includes estimating the weight values based on a ratio of a signal vector before despreading and the signal vector after despreading.
