- Abstract
- Provided is an apparatus and method for transmitting and receiving data. The method includes respectively estimating a carrier frequency offset (CFO) of data packets transmitted during a transmit opportunity (TXOP) period by a unit of a packet; calculating an average CFO of the estimated CFOs estimated during a window period for the data packets; and compensating an estimated CFO of a predetermined data packet to one of the estimated CFO of the predetermined data packet and the average CFO, and restoring the predetermined data packet.
