Abstract

See full text

User equipment is provided for receiving an OFDM signal. The user equipment includes a plurality of carrier processing chains and a carrier aggregation module, aggregating the signals received on each carrier processed by the plurality of carrier processing chains. The aggregation module delivers a set of aggregated signals of the plurality of carrier processing chains at the input of a Fast Fourier Transform module of a PHY layer processing subsystem of the user equipment. The Fast Fourier transform module is able to process a size of data according to a predetermined rate depending on the aggregated bandwidth of the set of aggregated signals of the plurality of carrier processing chains, and the carrier aggregation module includes at least one frequency shifter for frequency shifting carriers.
