Joint 2D-pilot-symbol-assisted-modulation and decision-directed frequency synchronization schemes for coherent OFDM
(2000) IEEE Acoustics, Speech, and Signal Processing Conference 5. p.2961-2964- Abstract
- A new frequency offset tracking approach for OFDM has been addressed. Two-dimensional pilot-symbol assisted modulation (2D-PSAM) is employed in coherent OFDM for channel estimation and it is based on inserting known symbols spread out through the 2D time-frequency grid. We show that these scattered symbols can also be employed to perform frequency synchronization. Maximum likelihood estimation has been derived for both time and frequency domains. Also, if a decision-guided strategy is used jointly with the 2D-PSAM signalling, an improvement in performance can be attained
