发明名称 CARRIER RECOVERY DEVICE AND METHOD, AND DEMODULATOR
摘要 A carrier recovery device includes a first carrier recovery unit configured to multiply a baseband signal by a first carrier to obtain a first demodulated signal, and generate the first carrier based on a first phase error in a pilot signal extracted from the first demodulated signal, a second carrier recovery unit configured to multiply the baseband signal by a second carrier to obtain a second demodulated signal, and generate the second carrier based on a second phase error in a pilot signal extracted from the second demodulated signal, and a selector configured to select one of the first and second demodulated signals which has been obtained by one of the first and second carrier recovery units whose carrier recovery operation has reached a predetermined steady state earlier than that of the other, based on the first phase error and the second phase error, and output the selected demodulated signal.
