This paper proposes a pilot-aided joint channel estimation and synchronization scheme for burst-mode orthogonal frequency division multiplexing (OFDM) systems. The scheme eliminate...
Orthogonal Frequency Division Multiplexing (OFDM) can provide a flexible usage of the spectrum by controlling individual subcarriers. Sets of subcarriers can be zero-modulated to a...
Abstract-- We address low-complexity, highly-accurate frequency offset estimation for MB-OFDM-based UWB systems. We discuss unique characteristics of the MB-OFDM systems, namely, d...
Adaptive interference cancellation is addressed in an orthogonal frequency division multiplexing (OFDM) system with a frame containing a number of temporally distributed pilot sym...
—In this paper we present a study on pilot aided time and frequency synchronization for Opportunistic Radio (OR) OFDM systems which apply adaptive subcarrier allocation technique...
