摘要

A method and devices for transferring data and information enabling an estimate of a wireless link between a source and at least one receiver using single carrier orthogonal frequency division multiplex scheme. The source : - spreads data from the time domain to the frequency domain, - replaces at least a part of spread data by at least one pilot sequence, - maps spread data which are not replaced by the at least one pilot sequence and the at least one pilot sequence replacing spread data on subcarriers, - executes an orthogonal frequency division multiplex modulation on the mapped data and the at least one mapped pilot sequence in order to form an orthogonal frequency division multiplex modulated symbol, - transfers the orthogonal frequency division multiplex modulated symbol to the receiver. At the receivers, the equalisation coeffients of the data located in the pilots positions are set to zero.
