چکیده

This paper proposes a novel method for designing two-channel and M-channel causal stable IIR PR filter banks using cosine modulation. In particular, we show that the PR condition of the two-channel IIR filter banks is very similar to the two-channel FIR case. Using this formulation, it is relatively simple to satisfy the PR condition and to ensure that the filters are causal stable. Using a similar approach, we propose a new class of M channel causal stable IIR cosine modulated filter banks. Design examples are given to demonstrate the usefulness of proposed approach.

Oversampled cosine-modulated filter banks with arbitrary system delay

In this paper, design methods for perfect reconstruction (PR) oversampled cosine-modulated filter banks with integer oversampling factors and arbitrary delay are presented. The system delay, which is an important parameter in realtime applications, can be chosen independently of the prototype lengths. Oversampling gives us additional freedom in the filter design process, which can be exploited ...

Discrete-coefficient linear-phase prototypes for PR cosine-modulated filter banks

In this paper, a method for the design of perfect reconstruction (PR) linear-phase prototypes for cosine-modulated filter banks with discrete coefficients is presented. Such prototypes are of great interest for efficient hardware implementations. The design procedure is based on a subspace approach that allows to linearly combine PR prototype filters in such a way that the resulting filter also...

Design of paraunitary oversampled cosine-modulated filter banks

In this paper we derive perfect reconstruction (PR) conditions for oversampled cosine-modulated lter banks. The results can be regarded as a generalization of the known work for critical subsampling. We show that in the over-sampled case we gain some additional degree of freedom, which can be exploited in the lter design process. This leads to PR prototypes with stopband attenuations being much...

A general formulation of modulated filter banks

This paper presents a general framework for maximally decimated modulated filter banks. The theory covers the known classes of cosine modulation and relates them to complexmodulated filter banks. The prototype filters have arbitrary lengths, and the overall delay of the filter bank is arbitrary, within fundamental limits. Necessary and sufficient conditions for perfect reconstruction (PR) are d...
