We consider the design of M-channel orthonormal filter banks using polynomial matrix EVD techniques. Modifications are proposed to a time-domain, polynomial EVD technique, known as SBR2, which enables it to be applied effectively to the task of FIR paraunitary filter bank design for use in subband coding. This algorithm is compared to a state-of-the-art FIR compaction filter design method. We show that higher coding gains are obtainable with our technique for a small number of algorithm iterations.
