Many algorithms for providing proportional delay differentiation and proportional loss differentiation have been proposed under wired networks. However, these algorithms suffer from low performance at encountering some distinct characteristics, such as location-dependent and time-varying channel capacity, which exist in wireless networks. This paper proposes a novel algorithm, Wireless Proporti...

A Compact planar slot antenna is proposed and developed for Ultra Wideband Applications. The antenna has compact size of 28 x 31 x 0.8 mm 3 . The antenna is fabricated with FR4 substrate and it is fed by Coplanar Wave Guide. The antenna is investigated experimentally to obtain required return loss, gain and radiation pattern characteristics. The antenna operates over a band between 3.1 GHz and ...

In this paper a high performance Ultra Wide Band microstrip bandpass filter is presented. The filter is designed using λ/4 short circuited stubs to improve the performance of UWB. The designed filter is based on 5th order chebyshev low pass prototype with .1 dB passband ripples. The filter with total size of 45×11 mm operates within 3.1310.4 GHz, produces a fractional bandwidth of 106%. The fil...

This paper presents the design a power amplifier (PA) for direct sequence ultra-wideband applications using 0.13 μm CMOS technology operating in a low band frequency of 3.1 GHz to 5.1 GHz. Current-reused technique is employed at the first stage to increase the gain at the upper end of the desired band. Cascaded common source configuration with shunt peaking inductor at the second stage helps to...

This paper presents a least-pth approach for the design of complex-coefficient FIR digital filters with low group delay in the minimax sense. Features of the proposed approach include: it does not need to adapt the weighting function involved and no constrains are imposed during the course of optimization. More important, the algorithm enjoys global convergence to the minimax design regardless ...

This paper investigates the problem of designing-nite precision one-dimensional (1-D) innnite impulse response (IIR) lters with prescribed magnitude, phase and stability constraints. The design problem is formulated as the minimization of a cost function incorporating these connicting requirements. The rst two elements of the cost function express magnitude and group delay errors between the de...

<p><span lang="EN-GB">The purpose of this study is to determine whether or not audit delay caused by financial stress, the committee, profit and loss company. This also considered a number independent criteria, such as severity situation, participation in loss. In addition this, it incorporates dependent variable known delay. work, quantitative descriptive research used. Secondary d...

a 48‑year‑old morbidly obese woman with a left medial meniscal tear and moderately severe degenerative joint disease (djd) reported for 14‑month follow‑up visit from arthroscopic surgery. she reported a resolution of pain, swelling and an improved range of motion (rom). the patient was first evaluated 14 months ago, and at that time was considered a strong candidate for total knee replacement d...

An integrated photonic True Time Delay phaser for phased array, based on an innovative technology, is here presented. The module versatility is showed by presenting more driving strategies matching different antenna features. The phaser insertion loss, the fluctuations of the excitation coefficients corresponding to the various driving configurations and the statistical modeling of the realizat...
