ABSTRACT
There is a need to select the 'first step up' modulation scheme for higher data rate frequency hopping systems. This is seen as one step in a longer journey where considerably higher data rates are used. In order to make this progression viable, the first step should be taken with a well proven modulation scheme. An ....etc

A Surveillance Robot with Hopping Capabilities for Home Security

Abstract
Most traditional home robots have always had problems with stairs, doorsills and other
obstacles that humans cross with ease in cluttered indoor environments. This paper
presents the development and characterization of a surveillance robot with hopping
capabilities for home security. The proposed robot can leap over obstacles. It can also roll
freely on flat floors and change its directions by the two-wheeled differential drive
system. It adopts the Zi ....etc

Design and Application of Radio Frequency
Identification Systems

Abstract

The recent world, development of effective technologies for linking the object
wireless information is being prompted in various fields. Radio frequency identification
(RFID) is the latest technology for automatic identification which allows the transmission
of a unique serial number wirelessly. The purpose of this paper is to review RFID systems
and its various components infrastructure. The components and features are still under
research and b ....etc

Multiple access (MA) schemes are used to simultaneously share available bandwidth in communication systems. In conventional MA applications a finite and contiguous amount of spectrum which is designated for a particular service is allocated to multiple users. Therefore, the use of designated radio spectrum is unconstrained and can be utilized in many ways to achieve maximum efficiency. Time division multiple access (TDMA), frequency division multiple access (FDMA), and code division multiple access (CDMA) are the three major MA techniques. In r ....etc

A Technique for Orthogonal Frequency Division Multiplexing
Frequency Offset Correction

Abstract:
The Orthogonal Frequency Division Multiplexing (OFDM) is a Multi Carrier Modulation technique employing Frequency Division Multiplexing of orthogonal subcarriers. It is also sometimes called as discrete multitone modulation (DMT). It is better than CDMA in high bit rate and Broadband Communications .It is a multi carrier technique, which is very sensitive to Frequency Offset between transmitter and receiver. Th ....etc

The High frequency attenuation in shielded distribution cable has been extensively studied. But in the case of solid dielectric cable, this has not been done. A solid dielectric cable has a bit more complex structure including the semiconducting bedding layers and a moisture barrier.high frequency loss is created by these sources.The purpose of these bedding layers is to seal the cable against moisture ingress and also accomodate for the thermal expansion of the cable. The cables studied here are the ones with a corrugated copper sheath and ....etc
