Abstract
A filterbank system is provided for reordering subbands of a wideband digital signal. The filterbank system extracts the subbands from a wideband digital input signal into an even channel number group of even channel number subbands and an odd channel number group of odd channel number subbands. The separation of even and odd channel number subbands provides an even channel grouping with guard bands between the even channel number subbands and an odd channel number grouping with guard bands between the odd channel number subbands. The filterbank system then reorders the even channel number subbands and the odd channel number subbands. The reordered subbands are then combined by combining the reordered even channel number subbands and odd channel number subbands into a wideband digital output signal.
