Three non-pilot based time- and frequency estimators for OFDM

Forskningsoutput: TidskriftsbidragArtikel i vetenskaplig tidskrift

Abstract

Time-domain maximum-likelihood (ML) estimators of time and frequency offsets are derived for three orthogonal frequency division multiplexing (OFDM) signal models: a pulse-shaped one-shot OFDM signal, a stream of multiple OFDM signals and an OFDM signal in a dispersive channel environment. We then develop structures to simplify their implementation. Simulation results show the relative performance and strengths of each of these three estimators.
