Design perfect reconstruction cosine-modulated filter banks via quadratically constrained quadratic programming and least squares optimization

•Formulate PR CMFB design as a QCQP with variables in special re-arrangement.•Dig out the algebraic relationship between PR conditions and NPR ones.•Propose an efficient two-stage method for PR CMFB design. In this paper, the design of perfect reconstruction (PR) cosine-modulated filter banks (CMFBs...
