Frequency domain estimation and time domain correction of CFO and STO offsets in OFDM system

OFDM can use frequency band efficiently and has strong characteristic for fading channel. But orthogonality collapse when carrier frequency offset and sample timing offset occur. Sample timing offset is represented as phase rotation and ISI. And Carrier frequency offset is represented as phase rotat...
