Carrier Frequency Estimation Algorithms for Digital Modulated Signals
Liang Wei-yang · Telecommunication Engineering · 2006
A modified ESPRIT(estimating signal parameter via rotational invariance technique) algorithm is used to estimate the carrier frequency.Six modulation schemes of interest are considered.Computer simulations show that the modified ESPRIT algorithm is characterized by its high accuracy and low estimation variance,and it has the advantages over those available of robustness and practicability.
