摘要：
An algorithm for least-asymmetric signal extension for two-band paraunitary FIR filter banks is derived. The development of the algorithm is governed by the symmetric signal extension method for perfect reconstruction filter banks with even-length linear-phase filters. The approach yields an equality-constrained least-squares problem which is solved efficiently. The computational load is evaluated and simulation results for comparison of least-asymmetric and circular signal extension are presented.
