| Abstract: | In this presentation we briefly introduces the matched-phase spectral subtraction method for noise reduction.Then an adaptive algorithm is programmed and a model of low system is built and simulated,based on the low signal-to-noise ratio.Finally the fact-data results prove that,in case of strong interference,the method can display good ability to the low signal-to-noise ratio system. |
