Abstract
Provided is an interleaving method that can reduce error occurring during transmission at a receiving end in an Orthogonal Frequency Division Multiplexing (OFDM) system. According to the interleaving method, transmitted data bits are recorded in an interleaving memory; and the stored data bits are read based on a predetermined sequence to perform symbol interleaving, tone interleaving and cyclic shift simultaneously. Also, to simplify the logic of the OFDM system, the data bits transmitted from an interleaver go through Fast Fourier Transform (FFT) mapping, and the FFT mapped data bits are modulated. In short, the logic can be simplified by performing FFT mapping followed by modulation.
