| Abstract: | Sub-band coding is a means to accomplish bandwidth compression of HDTV signals. Quadrature mirror filters (QMF) are often used in sub-band coding to eliminate aliasing between sub-bands. This paper presents principles of two-band integer-band nonrecursive QMF,proposes a QMF optimization method based on windows design, and gives two QMF design examples. |
