3-2 A Study on error correction technique applied to OFDM with frequency-selective interferences

Abstract

OFDM(Orthogonal Frequency Division Multiplexing) is an efficient modulation method for the digital terrestrial broadcasting. The proposed method is an error correction technique applied to OFDM with frequency0selective interference. In order ti detect interferences, the method use cariance of each carrier between received data and hard decision data. This method can be applied to any modulation format and any coding rate.
