FPGA Implementation of Trained Coarse Carrier Frequency Offset Estimation and Correction for OFDM Signals (Abstract Only)

Published: 22 February 2015 Publication History

Abstract

This paper develops an FPGA implementation of a trained coarse Carrier Frequency Offset estimation and correction scheme using MATLAB System Generator. The designed system is capable of supporting variable FFT sizes for Orthogonal Frequency Division Multiplexing signals and different pilot symbol structures making it compatible with a large number of wireless communication standards, unlike other work that is protocol specific. This design stands out from its more common implementations as it requires only one pilot symbol to be considered for synchronization by using a data-aided modified correlation scheme, allowing for an increase in throughput. The Bit Error Rate of the corrected signal received over an Additive White Gaussian Noise channel is compared to the case without correction. This scheme demonstrated increased performance throughput since only a single pilot symbol was used.
