Carrier frequency offset estimation of DAB receiver based on phase reference symbol
Hui Min Lu, Zaiwang Dong · IEEE Transactions on Consumer Electronics · 2000
Estimation of the carrier frequency offset is a key part of OFDM receivers. A new method to estimate coarse carrier frequency offset and fine carrier frequency offset in a DAB receiver based on an analysis of phase reference symbol is given. The result shows that the estimation function is almost linear to frequency offset.
