METHOD FOR DEMODULATING RECEIVED SIGNALS AND APPARATUS THEREFORE

WIPO Patent Application WO/2011/016670

A2

Disclosed are a method for demodulating received signals and an apparatus therefore which can maintain quality of signals and can reduce computational complexity. A demodulation method of a receiving device for receiving a plurality of signals modulated through a M-ary (M is a natural number of 1 or more) modulation method comprises the steps of: comparing channel frequency response power of a first channel with channel frequency response power of a second channel; selecting reference signals of a M number on the basis of the compared result; selecting signals corresponding to each of the selected reference signals of a M number to form couples thereof; and estimating transmitting signals from the signal couples of a M number composed of couples of the reference signals and the corresponding signals. Accordingly, the computational complexity is reduced from O (M2) to O (M).
