Abstract: A signal processing method and apparatus are disclosed. The signal processing method includes: receiving, by a first signal processing apparatus, a mixed signal; acquiring, by the first signal processing apparatus, an energy strength ratio of the mixed signal, where the energy strength ratio includes a ratio of energy strength of a signal sent by a first signal source and received by the first signal processing apparatus to energy strength of a signal sent by a second signal source and received by the first signal processing apparatus; and if the energy strength ratio is less than a first preset threshold, using, by the first signal processing apparatus, the signal sent by the second signal source in the mixed signal as an interference signal and separating the interference signal, and determining that a mixed signal obtained after the separation processing is the desired signal sent by the first signal source.

Abstract: The present invention provides a method. The method includes: performing coupling to acquire a first reference signal and a second reference signal from a transmit signal transmitted on a same transmit link at a transmit end; performing signal recombination according to the first reference signal and the second reference signal, to obtain a first interference cancellation signal and a second interference cancellation signal; enabling the first interference cancellation signal to pass through a simulated interference channel, and enabling the second interference cancellation signal to pass through the simulated interference channel; and coupling and output, to a same receive link at the local receive end, the first interference cancellation signal and the second interference cancellation signal that have passed through the simulated interference channel, and combining the first interference cancellation signal and the second interference cancellation signal with a signal received by the local receive end.
