....filters may be derived from different prototypes. TICSP Workshop on Transforms and Filter Banks Biorthogonal Modulated Filter Banks Two principal approaches can be observed for the design of biorthogonal cosine modulated filter banks with perfect reconstruction. The approach by Schuller et al. [SS96, Sch96, SK97] uses filter bank realizations that structurally guarantee perfect reconstruction for arbitrary system delays. It is mainly based on a factorization of the analysis polyphase matrix into a transform and special sparse matrices which are easy to invert. The inverse matrices are then used on the ....
....the analysis and synthesis prototype filters are also stated [HKN96] Furthermore, it can be shown that for certain combinations of filter lengths and overall system delay, some polyphase filters can only have one non zero coefficient. This case is not treated in the factorization proposed in [Sch96, SK97]. However, the factorization approach from Schuller et al. offers many advantages concerning the implementation of the filter bank. First of all, the structure automatically guarantees PR. This also holds true when using integer valued coefficients, because the same factorization coefficients are ....
