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

INTRODUCTION
WCDMA stands for Wide Band Code Division Multiple Access.
W-CDMA is a Third-Generation(3G) mobile wireless technology that promises much higher data speeds to mobile and portable wireless devices than commonly offered in today's market.
It is specified by 3rd Generation Partnership Project (3GPP).
It is the key technology for UMTS.
HISTORY
QUALCOMM , the first company to succeed in developing a practical and cost effective CDMA implementation for co ....etc

Abstract
The ordinary CDMA technology has the disadvantage of identifying the users using the appropriate signature of each user. Since many users tend to use the transmission media, there is always a chance for superimposition of signals that can cause interference in network.

The solution for this inconvenience comes in the form of interleaving which separates the users. This special form of CDMA technology offers some of the features of CDMA such as the dynamic channel sharing, mitigation of cross cell reference, asynchronous tran ....etc

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

Abstract
Wireless ad hoc networks provide a new dimension to computing by allowing a group of portable devices to talk to each other without any additional infrastructure and have been the focus of research in the area of wireless networks. CDMA has been gaining popularity as the multiaccess technique and is part of many wireless standards now. In this project we present techniques to improve performance of the CDMA based wireless ad hoc systems and present results based on extensive simulations. The resource utilization of network in a ....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
