A low-complexity method for the design of low-delay cosine-modulated filter banks

We present a new method for the design of the cosine-modulated filter bank with low complexity and low delay. The design of such a filter bank is formulated as a nonconvex optimization problem with equality constraints. An iterative scheme is developed to solve this optimization problem. To illustra...
