Frequency offset estimation with improved estimation range in UWB-OFDM systems
In this letter, we address a carrier frequency offset (CFO) estimator with a large estimation range for ultra-wideband multi-band orthogonal frequency division multiplexing (UWB MB-OFDM) systems. We find by simulations that the proposed CFO estimator yields an improved estimation range, maintaining the same estimation performance and complexity in comparison with the conventional estimator.
