METHOD AND DEVICE FOR TRANSFERRING DATA AND INFORMATION ENABLING ESTIMATION OF WIRELESS LINK BETWEEN SOURCE AND RECEIVER USING SINGLE CARRIER ORTHOGONAL FREQUENCY DIVISION MULTIPLEX SCHEME AND METHOD AND DEVICE FOR ESTIMATING THE WIRELESS LINK BETWEEN SOURCE AND RECEIVER USING SINGLE CARRIER ORTHOGONAL FREQUENCY DIVISION MULTIPLEX SCHEME

摘要

PROBLEM TO BE SOLVED: To provide a method for transferring data and information enabling estimating of a wireless link between a source and at least one receiver using single carrier orthogonal frequency division multiplex scheme.

SOLUTION: 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; and transfers the orthogonal frequency division multiplex modulated symbol to the receiver.
