METHOD, APPARATUS AND SYSTEM FOR SIGNAL PROCESSING

摘要

Provided in the embodiments of the present invention are a method, apparatus and system for signal processing, which are applied to the technical field of communications as well as which can improve the accuracy of phase noise compensation in the signal processing of an MIMO-OFDM system in which transmitting and receiving antennae do not derive from a common source, and reduce the phenomenon of signal distortion. The method for signal processing is used for a receiving apparatus and comprises: obtaining the phase of each of the transmitting antennae when the lth OFDM data symbol is transmitted; obtaining the phase of each of the receiving antennae when the lth OFDM data symbol is received; and according to the phase of each of the transmitting antennae when the lth OFDM data symbol is transmitted and the phase of each of the receiving antennae when the lth OFDM data symbol is received, compensating for a received signal of each of the receiving antennae by a compensation formula, so as to obtain a compensating signal of each of the receiving antennae. Provided in the embodiments of the present invention are a signal processing method, apparatus and system, which are used for signal processing.
