Assignee: SPECTRAL DSP CORP.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 6:
7. The system of claim 4, wherein the processor demodulates the M-point and duration point output time array by:
removing the appended cyclic prefix time array to generate an M-point input time array,
transforming the M-point time input array to the frequency domain by a discrete Fourier transform to generate a shaped M-point input frequency array,
utilizing a matched filter to generate a shaped M-point input filtered frequency array by multiplying the shaped M-point input frequency array and the matched filter,
applying a channel equalizer to the shaped M-point input filtered frequency array to generate a shaped M-point output filtered and equalized frequency array,
down sampling the shaped M-point output filtered and equalized frequency array to generate an N-point output frequency array, and
transforming the N-point output frequency array by an inverse discrete Fourier transform to generate an N-point offset Dirichlet kernel output time array.
