Abstract :
We propose a modification to a polynomial SVD technique, known as SBR2, which enables it to be applied effectively to the task of optimal FIR paraunitary filter bank design for use in subband coding. We compare our technique, namely the SBR2 coder, to a state-of-the-art FIR compaction filter design method. Here, we show that, in the particular case of a two-channel filter bank, high coding gains are obtainable with our technique for a small number of algorithm iterations.
