Multirate filterbanks have found applications in speech processing, image processing, communications, and in the development of new sampling theorems. This paper explores the relationship between sampling theorems and multirate filterbanks in the linear canonical transform (LCT) domain. The sampling identity and the interpolation identity for bandlimited signals in the LCT domain are discussed ...

Super-resolution theory aims to estimate the discrete components lying in a continuous space that constitute a sparse signal with optimal precision. This work investigates the potential of recent super-resolution techniques for spectral estimation in multirate sampling systems. It is shown in the first part of this paper that, under the existence of a common supporting grid, the joint frequency...

On theory of multisensor state fusion estimation, more research is a single rate synchronization problem, however, it is the multirate asynchronous problem often encountered in practice. Therefore, research on the state fusion estimation of asynchronous multirate multisensor have more practice application value. In this paple, by expand the dimension of the system state and measurements and by ...

This paper presents novel architectures of multirate hybrid cascade continuous-time/discrete-time !" modulators that take advantage of the potentially faster operation of the continuoustime part of the circuit, while keep a reduced sampling operation of the back-end discrete-time stages. Compared to conventional multirate !" modulators, the proposed architectures use a higher sampling rate in t...

Multirate Filtering techniques are used when conventional method becomes extremely costly and this technique is widely used in both sampling rate conversion system and in constructing filters with equal input and output rates. The basic concepts and building blocks in multirate digital signal processing are discussed here which includes down-sampler, upsampler and analysis/synthesis representat...

This paper deals with adaptive control of linear time-invariant systems with unknown parameters and with two sampling rates: a slower one for the output and a faster one for the input. It is known that intersample ripples often arise in the outputs of the closed-loop multirate systems although multirate control has interesting advantages. In this paper, a ripple-suppressed multirate adaptive co...

in general, the objective of distillation control is to maintain the desired products quality. in this paper, the performances of different one point control strategies for an aromatic distillation column have been compared through dynamic simulation. these methods are: a) composition control using measured composition directly. this method sufferes from large sampling delay of measuring device...

The objective of the paper is to present a decentralized control approach to interconnected multirate linear systems with synchronous sampling. Each subsystem is assigned a single sampling rate. It simplifies local controllers design. The overall discrete-time system exponential convergence is achieved at the common sampling period via the concept of the M-matrices. The overall original continu...
