RECEIVER HAVING A SIGNAL RECONSTRUCTING SECTION FOR NOISE REDUCTION, SYSTEM AND METHOD THEREOF

WIPO Patent Application WO2004032347

A8

A signal reconstructing section (50), a receiver having the signal reconstructing section (50), a communication system having the receiver, and a method for reducing noise in a transformed signal having a plurality of signal components and using the signal reconstructing section (50) are described. The signal reconstructing section (50) of the receiver has a detector (52) for detecting the transformed signal, decision modules (54) each having an input (58) coupled to output (60) of the detector, and a reconstructing module (56) having inputs (62) respectively coupled to output (64) of the decision modules (54). The reconstructing module (56) is adapted to reconstruct one or more subcarriers of the plurality of subcarriers a predetermined number of times to thereby form a noise- reduced transformed signal. Reconstruction of the one or more subcarriers is performed one at a time or two or more simultaneously.
