Patent ID: 7590166

Claim:
A method for receiving a plurality of signals having passed through a plurality of paths from a plurality of transmission antennas to a plurality of reception antennas in a mobile communication system that transmits/receives data at a high speed by means of the plurality of transmission antennas and the plurality of reception antennas, the method comprising the steps of: a) estimating a transmission signal of a specific path from a first received signal received through each of the plurality of reception antennas according to a preset criterion via a receiver; b) measuring an error component for each symbol of the estimated transmission signal via an error detector; c) performing an error correction for symbols having a corresponding error component exceeding a preset value via the error detector; d) detecting transmission data from all symbols including the error-corrected symbols through a predetermined signal reverse-processing procedure via the error detector; e) reconstructing a transmission signal from the transmission data through a predetermined signal processing procedure via a signal reconstruction unit; f) subtracting the reconstructed transmission signal from the received signal and generating a second received signal via a subtractor; and g) repeating steps a) through f) until transmission data of all paths are detected from the second received signal.
