ABSTRACT:
Method and Apparatus for controlling combining coefficients of multiple receive antennas according to the channel conditions in a mobile communication system, to improve data restoration performance. A mobile station detects preamble, pilot and data from a signal received from a base station via the multiple receive antennas, measures a channel correlation from the detected preamble, classifies time-domain/frequency-domain intervals having a channel correlation exceeding a predetermined threshold as calculation regions, and calculates MMSE coefficients for the calculation regions. In this way, the mobile station finds the optimal coefficients for combining the signal received via the multiple receive antennas, thereby optimizing the reception performance.
