System and method for extracting acoustic signals from signals emitted by a plurality of sources

摘要

A system for extracting one or more acoustic signals from a plurality of source signals emitted by a plurality of sources, respectively, in an environment, the system comprising an array of microphone receivers for receiving the one or more acoustic signals from the environment and transmitting the signal to a signal processor, wherein the signal processor is arranged to estimate the plurality of source signals using the data received by array of receivers, the signal processor is further arranged to perform an operation on the data received by the array of receivers with the estimated source signals to provide an estimate of the impulse response of the environment, wherein the data received by the array of receivers is input to the estimate of the impulse response of the environment to provide an output comprising a plurality of channels, wherein one or more of the channels correspond to the one or more acoustic signals from one of the plurality of sources, respectively.
