METHOD, APPARATUS AND SYSTEM FOR SIGNAL PROCESSING

摘要

Embodiments of the present invention provide a signal processing method, an apparatus, and a system, which are applied to the communications field and can improve precision of phase noise compensation during signal processing in a MIMO-OFDM system in which receive antennas or transmit antennas do not share a common oscillator and reduce cases of signal distortion. The signal processing method is applied to a receiving apparatus, and includes: acquiring a phase of each of transmit antennas when the l th OFDM data symbol is sent; acquiring a phase of each of receive antennas when the l th OFDM data symbol is received; and compensating received signals of each of the receive antennas according to the phase of each of the transmit antennas when the l th OFDM data symbol is sent and the phase of each of the receive antennas when the l th OFDM data symbol is received and by using a compensation formula, to obtain compensated signals of each receive antenna. The embodiments of the present invention provide a signal processing method, an apparatus, and a system, which are used for signal processing.
