| titleOfInvention | Signal processing method and apparatus |
| abstract | The present invention relates to the field of communications. Disclosed are a signal processing method and apparatus, which can implement self-interference cancellation when IQ imbalance exists in a communications system. The specific scheme comprises: a signal processing apparatus acquires a digital baseband reference signal, a self-interference reference signal and a frequency-domain baseband signal; the signal processing apparatus acquires, according to the digital baseband reference signal, a basic reference signal and a mirror reference signal that are mirrored to each other; the signal processing apparatus estimates an estimated value of a first comprehensive response and an estimated value of a second comprehensive response according to the basic reference signal, the mirror reference signal and the self-interference reference signal; and the signal processing apparatus calculates a self-interference signal according to the estimated value of the first comprehensive response, the estimated value of the second comprehensive response, the basic reference signal and the mirror reference signal, so that the signal processing apparatus performs self-interference cancellation on the frequency-domain baseband signal. The present invention is used in signal processing. |
