— Decision directed channel tracking (DDCT) at high fade rates in OFDM based systems is addressed in this paper. Existing DDCT algorithms like the expectation-maximization (EM) a...
The estimation and tracking of the fractional carrier frequency offset (CFO) is a crucial issue in the implementation of orthogonal frequency division multiplexing (OFDM) systems....
Abstract—This paper proposes a new scheme based on information theoretical criteria to estimate the Channel-ImpulseResponse (CIR) length, whose accurate estimate represents one o...
