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

Claim 13:
14. A non-transitory computer readable medium having instructions stored thereon for modulating a signal which, when executed by a processor of a transceiver, causes the processor to carry out the steps of:
receiving an input signal; and
modulating the input signal to form Dirichlet kernels in a time domain to generate an offset Dirichlet kernel output time array, each Dirichlet kernel having a main lobe and a plurality of side lobes,
wherein modulating the input signal suppresses a peak to average power ratio of the offset Dirichlet kernel output time array by reducing the plurality of side lobes of each Dirichlet kernel and respective amplitudes of the side lobes, and wherein, in modulating the input signal, a spectral guard interval having a duration exceeding a largest delay spread interval is inserted between spectral replicates of the input signal in an M-point input frequency array.
