Single-channel blind source separation method of surface electromyogram signals of human body

The invention discloses a single-channel blind source separation method of surface electromyogram signals of a human body and belongs to the technical field of electronic information. The separation method is characterized in that an electromyographic signal preprocessing module with multichannel input and single-channel output and a single-channel blind source separation module with single-channel input and multichannel output are adopted. The method comprises the following steps: multichannel surface electromyographic signals are added and mixed directly to form single-channel signals for transmission through the electromyographic signal preprocessing module; ultimately, under the condition that later pattern recognition effects are not affected, the single-channel blind source separation module restores single-channel signals simply, rapidly and effectively into source signals, namely electromyographic signals to realize the output of multichannel output ports and replace the traditional transmission technology which adopts multiports and multichannels or multiplexing and demultiplexing multichannels. The method provided by the invention can effectively reduce the number of transmission channels to achieve the aims of lowering hardware complexity and saving equipment cost.
