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.
