Abstract :
We propose the quadratic-constrained formulas for the design of linear phase cosine modulated paraunitary filter banks. 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
