Abstract

We propose a blind and robust monitoring scheme of frequency offset drift based on sparse fast Fourier transform, by which optimum performance and minimum hardware-cost of frequency offset estimation are achieved simultaneously. The performance is experimentally verified with 28 Gbaud QPSK, 16- and 64-QAM signals.
