[0097] figure 1 is a flow chart of the present invention.
[0098] The core content of the present invention mainly includes three parts: (1), the establishment of the Ad-hoc network shown in step a and the initialization of the audio acquisition module shown in step b; (2), the multi-channel dimension-based method shown in step d. Single-node speech enhancement of nano-filter; (3) Multi-node iterative speech enhancement based on multi-channel Wiener filter shown in step f.
[0099] like figure 1 As shown, the present invention specifically comprises the following steps:
[0100] (1), establishment and initialization of Ad-hoc network
[0101] Step a, setting up multiple microphone arrays, and establishing a distributed microphone array network based on an Ad-hoc network composed of multiple microphone arrays; any two network nodes can communicate with each other.
[0102] Ad-hoc networks are also called ad hoc ad hoc networks. Since the network does not need additional i...
