Title :
The implementation of estimation and correction of carrier frequency offset of COFDM system in DAB receiver
Abstract :
Estimation of the carrier frequency offset is a key part of COFDM receivers. A novel hardware scheme of carrier frequency offset estimation and corrections of COFDM system in DAB (digital audio broadcast) receiver is implemented on FPGA. It has been embedded in the monolithic DAB channel decoder and it also can be utilized in other OFDM system after some modification.
