Frequency estimation based on fast Fourier transform for QAM signals in optical transmission systems

Not Accessible

Your library or personal account may give you access


A frequency estimation method is presented based on fast Fourier transform of the symbol’s phase angle. The method does not require removing modulated data phase and can be used for QAM constellations. The principle of the algorithm is proven and a diagram is proposed to illustrate the algorithm. Numerical simulations are carried out to corroborate the performance analysis.
