ABSTRACT:
The present invention relates to a maximum ratio combining method of spatial-filtered received signals and an apparatus using the same. For this purpose the present invention provides a method for receiving signals by using a plurality of antennas that form a linear array antenna, multiplying a plurality of weight vectors by the received signals, summing the multiplication results for each weight vector, and combining the summing results by using maximum ratio combining. According to the present invention, signals are dividedly received by applying spatial filtering for a receiving direction of each signal and performance can be improved by combining the received signals by using maximum ratio combining. In addition, performance of an MRC-rake and a beam forming gain can be simultaneously acquired according to the present invention.
