The effects on the heads of human of the electromagnetic waves produced by mobile antenna are presented in this paper. The interactions between electromagnetic energy and the human head are modelled using a COMSOL simulation and the distributions of the produced electric field and resultant temperature inside the human head are obtained. A planar I...

This paper presents a planar ultra-wide band (UWB) sensing antenna accompanied with a monopole narrow band communicating antenna for interweave cognitive radio (CR) applications. The UWB antenna bandwidth covers the entire band specified for UWB applications (3.1–10.6 GHz). In addition to the varactor diode, a PIN diode is attached to the communica...

A low profile and compact size cognitive radio (CR) sensing/communicating antenna system is presented in this paper. A slotted elliptical monopole antenna (SEMA) is proposed as an ultra-wideband (UWB) sensing antenna for the CR system, while the CR communication relies on a triangular reconfigurable monopole antenna. Two PIN diodes are attached to...

Impulsive noise is considered as one of the major source of disturbance in the state-of-the-art multicarrier (MC) communication systems. Therefore, several techniques are being constantly proposed to eliminate the effect of such noise. In this work, a time domain matrix interleaved is compiled with a single carrier frequency domain equalizer (SC-FD...

This paper presents a compact wide-slot ultrawide-band (UWB) antenna with reconfigurable and sharp dual-band notches compatible with the underlay cognitive radio systems. The antenna slot and tuning stub are reshaped in such a way that the proposed antenna operating bandwidth extends along the frequency band specified for UWB applications (3.1-10.6...

The Multiple-Valued Logic (MVL) is one of the keys to build the future logic circuits. One of the most important logic units is Field Programming Gate Array (FPGA). Multiple-valued FPGA structures have interconnections less than that in binary FPGAs. Because the inherent dominate delay, power and size the Multiple-valued logic offers overcoming suc...

Analog filters constitute indispensible component of analog circuits and still playing an important part in interface with analog real world. realizing filters with odd order is preferred because of its time response . Therefore, this paper is conducted to introduce a new generalized Chebyshev – like approximation for analog filters. The analyses p...

Control of DC/DC boost converter is a complex task due to the nonlinearity in the converter and that introduced by the external changes. This paper describes a robust sliding mode controller for the control of DC/DC boost converters. As well as, dynamic equations describing the boost converter are represented. Also, sliding mode controller is model...
