—This paper presents a sampling frequency offset estimation in time domain for discrete multitone (DMT) systems. Cyclic prefix (CP) enables this estimation without pilots. The pr...
This paper presents a blind subspace-based tracking scheme for precoded MIMO-OFDM systems over rapidly time-varying wireless channels. Subspace-based tracking is normally consider...
