Reference signal for phase tracking insertion

Abstract

The present invention relates to a method implemented by computer means of a communicating entity, for inserting a reference signal for phase tracking, said communicating entity using a discrete Fourier transformation spread orthogonal frequency division multiplexing modulator, characterized in that the method comprises: obtaining a succession of signal samples by inserting said reference signal for phase tracking within a succession of data samples, according to at least one insertion pattern chosen among pre-defined patterns with respect to predetermined criteria of communication conditions, and feeding said modulator with a succession of signal blocks obtained from said succession of signal samples, so as to apply the discrete Fourier transformation after the insertion of the reference signal for phase tracking.
