摘要：This paper shows that the phase system resulting from the quadratic-cone-programming (QconeP) feasibilitycheck (FC) can be further improved through adopting a furtherstep nonlinear optimization. Although the QconeP feasibilitycheck (QconeP-FC) design technique can get a sufficiently accurate phase system, the further-step nonlinear optimization can further reduce the peak errors of both frequency response (FR) and phase response. Clearly, this new approach includes two-step optimizations. The first one uses the QconeP-FC approach, and the second one employs a further-step nonlinear optimization. Incorporating the nonlinear optimization into the QconeP-FC approach yields an accuracy-enhanced digital phase system. An illustrative example is included to demonstrate the performance of this two-step-optimization design methodology.
