Abstract
A carrier aggregation controller for providing an aggregated baseband signal from a plurality of baseband signals is provided. The controller comprises an accumulating memory, a selector and a time domain transformer. The selector is configured to add at least a first list of frequency domain samples obtained for the first baseband signal to first consecutive locations in the accumulating memory centered at a first preset location associated with the first baseband signal, and a second list of frequency domain samples obtained for the second baseband signal to second consecutive locations in the accumulating memory centered at a second preset location associated with the second baseband signal. The time domain transformer is configured to apply at least an inverse discrete Fourier transform to the frequency domain samples accumulated in the accumulating memory, obtaining the aggregated baseband signal.
