Blind CFO Estimation for Zero-Padded OFDM over Underwater Acoustic Channels

Zhou, Wei2012

… three existing blind carrier-frequency-offset (CFO) estimators when they are applied to estimate the residual Doppler shift for zero-padded OFDM transmissions over underwater acoustic channels: the null subcarrier based method, the O-M algorithm, and the Y-G algorithm. Performances of these …

A new data rotation syncrhonization scheme for CP based OFDM systems

SHI MIAO2004

… for symbol timing and carrier frequency offset (CFO) estimation of orthogonal frequency-division multiplexing (OFDM) systems. We first analyze Beeka??s cyclic prefix (CP) based joint ML estimator [2] and find that its performance can be improved when the average energy of the CP increases. We …

Advanced methods in automatic modulation classification for emerging technologies

Li, Hong

… it is simple yet accurate enough parameter estimation with reduced complexity. Second the incorporation of antenna arrays offers an effective ability to combat fading. Furthermore, a practical array-based qHLRT classifier scheme is implemented, which applies maximal ratio combining (MRC) to …
