Method and device for transmitting items of OFDM data

Abstract

The invention relates to a transmission method for transmitting a plurality of binary words in an OFDM symbol. The transmission method comprises, in particular, a modulation step (200), wherein a binary word to be transmitted is associated with a particular sequence Cp i having a size N obtained by cyclically shifting a root sequence, a step (201) of creating a first vector, wherein elements from at least two sequences are periodically interleaved, a step (202) of obtaining a second vector having K elements by applying an inverse discrete Fourier transform to the first vector, and a step 203) of transmitting, on K OFDM subcarriers, an OFDM symbol representative of the K elements of the second vector. The invention also relates to a method for receiving one of at least one binary word transmitted according to the transmission method, and to transmitting and receiving devices for implementing the methods.
