摘要
The invention relates to a source data modulation device, delivering a multicarrier signal. According to the invention, such a device comprises: a preprocessing stage (21), comprising at least two preprocessing modules (211, 212, 213) each capable of processing said source data according to a type of modulation at multiple carriers separate; a mathematical transformation stage (22) comprising at least one mathematical transformation module (221, 222); a post-processing stage (23), comprising at least two post-processing modules (231, 232, 233) each capable of processing said transformed data according to a distinct type of multicarrier modulation; selection means (113) of one of said pre-processing modules and one of said corresponding post-processing modules, as a function of a type of multicarrier modulation to be implemented.
