CFO estimation and correction in a WiMAX-like FBMC system

Abstract

In this contribution we evaluate pilot-based carrier frequency offset (CFO) estimation and its correction in a filter bank based multicarrier (FBMC) system. We show that by applying certain pilots designed specifically for filter banks, the CFO can be accurately estimated. The performance evaluation is done in a hypothetical WiMAX scenario in which an FBMC system would substitute OFDM maintaining as much physical layer compatibility as possible.
