Interpolator is an important sampling device used for Multirate filtering to provide signal processing in wireless communication system. There are many applications in which sampling rate must be changed. Recent advances in mobile computing and communication applications demand low power and high speed VLSI DSP systems. In this paper, an efficient method has been presented to implement low powe...

Abstract:Multirate technique is necessary for systems with different input and output sampling rates. Recent advances in mobile computing and communication applications demand low power and high speed VLSI DSP systems [4]. This Paper presents Multirate modules used for filtering to provide signal processing in wireless communication system. Many architecture developed for the design of low comp...

This paper presents observer-based robust fault detection for multirate sampled-data linear system. It is assumed that all plant inputs are updated with a unique sampling period and that the plant outputs are sampled uniformly at integer multiples of the input sampling period. A state observer is constructed, as in the single rate case, and a residual generator is derived. The paper shows that ...

Any digital processing performed on a signal with larger nyquist interval requires more computation than signal processing performed on smaller nyquist interval. The sampling rate alteration generates the unwanted effects in the system such as spectral aliasing and spectral imaging during signal processing. Multirate-multistage implementation of digital filter can result a significant computati...

This paper deals with the task of obtaining approximated models of discrete-time systems by the use of parametrical identification algorithms. Firstly, a filter-based identification method used to obtain a parametric model from a series data of the impulse of the system based in Leverrier’s algorithm is revised. A second method based on least squares minimization that allows identifying the dis...

Abstract: In this work, Multirate Output Feedback (MROF) controllers namely Fast Output Sampling (FOS) controller and Periodic Output Feedback (POF) Controller are designed using Generalized Predictive Control (GPC). The performances of the designed controllers are evaluated by applying the same for the active vibration control of a smart structure. The closed loop responses of the controllers ...
