Monopole antenna is one of the famous low-profile antennas because of its features of light in weight and easy to install. However, it can only be operated in lower gain and bandwidth due to the easiness of noise affecting. As other types of antenna, monopole antenna uses perfectly electrical conducting...

In this paper, a research on coastal Radar to support C4ISR (Command, Control, Communications, Computers, Surveillance and Reconnaissance) was carried out.This coastal Radar has an advantage of easy to be transported in order to observe seas/coastal areas in different locations. The Radar technology...

In this paper, design and implementation of dual band 2-Way Wilkinson Power Divider (WPD) is presented. This WPD can used for frequency of 456 MHz (X-Band Radar) and frequency 600 MHz (S-Band Radar). The Dual Band WPD used a two-section broadband method which consists only of cascaded sections of branch-lines...

Spectral slicing of a supercontinuum source has a good prospect in the applications of the wavelength-division-multiplexing (WDM)- radio-over-fiber(RoF) systems. A comb filter based on superstructure fiber Bragg grating (SSFBG) to slice the supercontinuum spectrum generated in the photonic crystal fiber...

A surge of interest toward design and implementation of green networks are emerging in recent years. One obvious trend to reduce energy consumption of major active network components is to craft backbone network architecture that takes into consideration traffic grooming of low-rate IP traffic as well...

As an efficient approach to increase data rate in wireless communication, vertical Bell laboratories layered space-time (V-BLAST) has been widely studied. In this paper an improved V-BLAST decoding algorithm, ordered group interference suppression (O-GIS), is presented, which reduces the error rate by...

An electronic product has to comply with a myriad of EMC requirements before it can be marketed globally. Radiated Emission is one of the EMC requirements which constantly poses a challenge to many circuit designer due to the ever increasing speed of PCB clocks. Consequently, in the product it is essential...

Compressive sensing (CS) is a new signal acquisition framework for sparse and compressible signals with a sampling rate much below the Nyquist rate. In this work, we consider the problem of perturbed compressive sensing (CS) with uncertainty in the measurement matrix as well as in the measurements. In...

Generally the Radio Base Station(RBS) designs include three cases: (1) The equipment room is separated with the iron tower; (2) The equipment room is enclosed by the four feet of the iron tower; and (3) The iron tower is erected on the top of equipment room. With respect to the above cases, a rational...

Earthing is the foundation of lightning protection of the RBS (radio base station), providing a way for discharging the lightning current. Equipotential bonding can protect equipment from lightning attack, providing a potential reference point for all equipment. There are two methods for the equipotential...

Some research have explained the difference of effect between power frequency current with lightening current injecting into earthing network. The surface of the earthing body can be approximately regarded as equipotential surface in the case of power frequency no matter how large the area of an earthing...

Vehicular Ad-hoc Networks (VANETs) represent a rapidly emerging, particularly challenging class of Mobile Ad Hoc Networks (MANETs). VANET often suffer from security attacks because of its features like open medium, changing its topology dynamically, lack of central monitoring and management, cooperative...

The novel indoor localization system is proposed and demonstrated using white LED ceiling lights. The mean of distance errors shows that is 3.57 cm in the simulation setup of 8 m x 8 m x 3 m, and is 0.65 cm in the experimental setup of 0.3 m x 0.3 m x 0.5 m in the positioning system.

For the development of distributed control system (DCS), a new plant-wide DCS main and auxiliary control integration network was introduced, that means the whole plant is equipped with Unit Plant DCS. Unit Plant DCS public network and the whole plant auxiliary plant control network Combine into a new...

In connection with the shortcomings of the current power transmission line inspection Unmanned Aerial Vehicle (UAV), a new electric power inspection fixed-wing UAV is developed to improve the efficiency. The images of the line defects and potential problems are located and collected with the aerial views...
