Filter bank - Wikipedia
WEBThe simplest approach to design a multi-dimensional filter bank is to cascade 1D filter banks in the form of a tree structure where the decimation matrix is diagonal and data is processed in each dimension separately.

WEBReconstruction Filter Banks •A perfect reconstruction (PR) filter bank is any filter bank whose reconstruction is the original signal, possibly delayed, and possibly scaled by a constant. •In this context, critical sampling (also called “maximal downsampling”) means that the downsampling factor is the same as the number of filter ...
Analytic cascaded filterbanks for multicarrier modulation
WEBAug 23, 2017 · The authors propose a cascade of filterbanks which produce nearly analytic waveforms. They also design a class of 3-band filterbanks whose high-pass filters are structurally complex conjugate pairs, which reduce the complexity of the design.

WEBAug 1, 2017 · A novel design of a wide bandwidth polyphase up-sampling filter bank formed by cascading external shaping filters, arbitrary interpolators and two stages of polyphase channelisation, which spans a two-sided baseband bandwidth of 960 MHz.
Nonuniform Filter Banks: New Results and open Problems
WEBJan 1, 2003 · A nonuniform filter bank (FB) is one whose channel decimation rates need not all be equal. While the theory and design of uniform FBs is a very well developed subject, there are several interesting open issues in the area of nonuniform FBs.
Synthesis Filter Bank - an overview | ScienceDirect Topics
WEBThe cascade channelizer is designed to be a perfect reconstruction filter process, a process enabled by the use of the Nyquist filter-based analysis filter bank. The Nyquist filter exhibits imperfect response related to nonzero levels of in-band ripple and finite stopband attenuation levels.
Optimum low complex tree structured filter banks using overlap …
WEBTree structured filter bank is obtained by cascading two channel filter banks in a uniform manner. This paper proposes an optimum tree structured filter banks using Parks McClellan algorithm which minimizes the error between desired and actual response.
