| Abstract: | We propose the quadratic constrained formulas for the design of linear phase cosine modulated paraunitary filter banks given in references .Using these formulae,we can,directly,optimize the prototype filter coefficients in a quadratic form.A design example is also given to demonstrate these formulae in this paper. |
