We consider multirate digital control systems which consist of an interconnection of a continuous-time nonlin-ear plant (described by ordinary diierential equations) and a digital lifted controller (described by ordinary difference equations). The input to the digital controller consists of the multirate sampled output of the plant and the input to the continuous-time plant consists of the mult...

Distributed Source Coding (DSC) based signal processing applications are ideal candidates for multirate transmissions in Wireless Sensor Network (WSN). In this paper, we propose a novel MAC-PHY approach in WSN to achieve energy efficiency using multirate desirable for the DSC based signal processing applications. Our approach is different from the common multirate research in link adaptation, t...

In the context of time-domain simulation integrated circuits, one often encounters large systems coupled differential-algebraic equations. Simulation costs these can become prohibitively as number components keeps increasing. an effort to reduce a twofold approach is presented in this paper. We combine maximum entropy snapshot sampling method and nonlinear model order reduction technique, with ...

The Farrow structure can be used for efficient realization of adjustable fractional-delay FIR filters, but despite its efficiency compared to other approaches, its implementation complexity grows rapidly as the bandwidth approaches π. To reduce the complexity, a multirate approach has been proposed. In this approach, the input signal is first interpolated by a factor of two via the use of a fix...

Multirate schemes for conservation laws or convection-dominated problems seem to come in two flavors: schemes that are locally inconsistent, and schemes that lack mass-conservation. In this paper these two defects are discussed for onedimensional conservation laws. Particular attention will be given to monotonicity properties of the multirate schemes, such as maximum principles and the total va...

In the paper retiming of DSP algorithms exhibiting multirate behavior is treated. Using the non-ordinary marked graph model and the reachability theory, we provide a new condition for valid retiming of multirate graphs. We show that for a graph with n nodes the reachability condition can be split into the reachability condition for the topologically-equivalent unit-rate graph (all rates set to ...

Abstract—This paper presents development of a new adaptive structure based on multirate filter and testing the same for deterministic, speech and music signals. A new class of FIR filtering algorithm based on the multirate approach is proposed. They not only reduce the computational complexity in FIR filtering, but also retain attractive implementation related properties such as regularity and ...

An optimal control strategy based on Two-Point-Multirate Controllers (TPMRCs), is used to design a desirable excitation controller of a hydrogenerator system, in order to enhance its dynamic stability characteristics. In the TPMRCs based scheme, the control is constrained to a certain piecewise constant signal, while each of the controlled plant outputs is detected many times over a fundamental...
