| In this paper some new results for multidimensional m-band bi-orthogonal lter banks are presented. In the rst part of the paper we introduce the ladder structure as a method for the design and implementation of aforementioned lter banks. The theory of ladders and the relation to lter banks is presented. The second part of the paper focuses upon linear phase conditions for bi-orthogonal lter b...

T he Hough transform is a useful technique in the detection of straight lines and curves in an image. Due to the mathematical similarity of the Hough transform and the forward Radon transform, the Hough transform can be computed using the Radon transform which, in turn, can be evaluated using the central slice theorem. This involves a two-dimensional Fourier transform, an x-y to rmapping and a ...

| A digital lter is one of the fundamental elements in the digital video transmission, and a multiplier acts as the key factor that determines the operation speed and silicon area of the lter. Even though the coe cients to the lter are desired to be programmable, it is possible to change coe cients in the vertical y-back interval of television receivers. This allows the preloadability of coe ci...

The noise predictive structure of DFE is attractive for the equalization of the coded modulation signals. In this paper, a blind predictive constant modulus (CM) decision feedback equalizer (PCM-DFE) is presented and analyzed. The PCM-DFE employs the CM linear equalizer as its forward lter and a feedback lter that optimizes the CM cost of the decision variable. It is shown that for any xed forw...

A CMOS phase-shift oscillator that uses a phase shift in the conduction of heat is proposed. The oscillator consists of an inverting ampli ̄er and a feedback thermal ̄lter that are integrated on a silicon chip. The thermal ̄lter consists of a polysilicon heater and a MOSFET thermosensor separated from each other by a SiO2 heat-conducting layer. 1 An input signal for the ̄lter travels from the heate...

In this paper, the problem of modeling head-related transfer functions (HRTFs) is addressed. Traditionally, HRTFs are approximated in real-time applications using minimum-phase reconstruction and various digital lter design techniques, yielding FIR or IIR structures. In this work, binaural auditory modeling has been applied to HRTF analysis and lter design methods have been compared from the au...

This paper presents a receiver lter, based on V olterra functions, for a direct-sequence code-division-multiple-access (DS-CDMA) system. The envisaged application would be cellular tele-phony, where the receiver will be required to be adaptive due to changes to the channel characteristics. The results obtained from the V olterra lter are compared against the linear minimum-mean-square-error (MM...

25 Modeling and simulation of a network interface handling two priority levels. We propose a scheme called Double Queue Scheme to reduce the eeects of local jobs' communication on the performance of parallel jobs. It divides the only one input and output queues in traditional network interfaces into two ones. One is for the communication of parallel jobs, and the other is for the communication ...
