This paper deals with the design of cosine-modulated QMF banks satisfying the perfect-reconstruction property (PR). This problem has been formulated as a novel quadratic-constrained least-squares (QCLS) minimization problem in which all constrained matrices of the QCLS optimization problem are symme
