Abstract :
This paper presents an algorithm for designing an FIR paraunitary filter bank when one or several filters are given. The algorithm is based on the properties of the balanced state-space representation of the polyphase matrix. We show that this representation may be computed via a single RQ decomposition thus gaining significant efficiency with respect to previous work. Application of the algorithm to signal-adapted filter banks is also discussed
