A method and device for mixing and separating a plurality signals. In the mixing method, each of the m signal Si(t) to be mixexd within a time perid [T0, T1] is sampled for n samples Si(tj), j=1,2 . . . n, wherein tepsi[T0, T1], T0, T1 epsiR, t is time variable. Each sample is multiplied by a coefficient function iaj(t) which is a linear independent set (i=1,2 . . . m, j=1,2 . . . n), thus obtaining m transformed signals for Si(t):By summing above m transformed signals obtains the mixed transformed signals are obtained:As to the separating method, the coefficient function iaj(t) is a linear independent set (i=1,2 . . . m, j=1,2 . . . n), therefore Si(tj) are the unknown of mxn linear equation set and can be solved by known linear algebraic method.
