Original Abstract

This contribution is focused on a carrier frequency offset elimination problem. The carrier frequencies of both the transmitted modulated signal and the local receiver oscillator may differ due to many known phenomena. However, the carrier waveform with an accurate frequency of received modulated signal is needed to perform a correct demodulation. Thus the carrier frequency offset is needed to be estimated and eliminated. Two optimization methods utilized for the indirect frequency estimation are compared in this paper. The steepest descent method and Newton’s method are implemented in Matlab and simulated. The time dependencies of phase offset estimates and recovered message signal are the results of simulation.
