Abstract

This paper examines the application of a packet format that we introduce for Doppler scaling estimation in multicarrier signals. Both orthogonal frequency division multiplexing (OFDM) and filterbank multicarrier (FBMC) signals are examined in an at-sea experiment. We also investigate the use of non-uniform fast Fourier transform (NUFFT) for compensation of Doppler scaling effects. The proposed packet format takes advantage of a few null subcarriers that are introduced for detection of the Doppler scaling that have been introduced due to the mobility of the communicating vehicles.
