  • FFT/IFFT clock adjustment
    Patent number: 8570851
    Abstract: A receiver for processing a signal in which data symbols are each represented by the energy at each of a plurality of carrier frequencies, the receiver comprising: an analogue to digital converter for periodically sampling the signal and generating a corresponding digital sample; a Fourier transform unit having a plurality of input bins for receiving samples generated by the analogue to digital converter and being arranged to, in dependence on the samples, generate outputs representing the energy in the signal during a sample period at each of a plurality of frequencies including the carrier frequencies; and a symbol estimator for estimating a symbol present in the signal during a sample period in dependence on the outputs of the Fourier transform unit; wherein the number of the input bins is greater than the total number of carrier frequencies and during each sample period the number of the outputs in dependence on which the symbol estimator performs symbol estimation is less than the number of input bins.
    Type: Grant
