摘要：

Novel structures for six-channel linear-phase paraunitary filter banks (LPPUFBs) are presented, which are inherently lossless, regardless of the accuracy of their coefficient representation. This is achieved by using quaternion arithmetic, at the expense of increased computational load. The results are interesting from the finite-precision implementation point of view, and supplement our previous works on quaternionic structures for four- and eight-channel PUFBs.
