Blind signal source separation (BSS) improvement technology

摘要

As for this disclosure, blind signal source separation (BSS) the signal processing technology which can improve the efficiency of law is described. In detail, as for the technology which is described, the signal which differs before the executing the BSS method the pretreatment step which is useful in order mutually non it correlates to convert is presented. In addition, the technology which is described furthermore non correlating converting can do the signal which differs after the executing the BSS method, you propose also the after-treatment step of option. As for these technologies, for example, especially it is useful in order to improve BSS efficiency making use of the aural signal where correlate high-level from two microphones and the like which have been approached mutually spatially.
