There have been remarkable growths in wireless communication networks in recent years; this is because of its merits over the wired networks such as Mobility and convenience. Wireless networks transmit the signal over the open air via radio waves of different frequencies, this makes it to be Continue reading
In this study, we follow the standard proposal IEEE 802.12.3a to implement the MB-OFDM UWB system in C programming language. We also analyze the system performance in the Continue reading
Recent popularity of the IEEE 802.11b Wireless Local Area Networks (WLANs) in a host of current-day applications has instigated a suite of research challenges. The 802.11b WLANs are highly Continue reading
This paper proposes a high performance, single-stage inverter topology for grid connected PV systems. The proposed configuration can not only boost the usually low photovoltaic (PV) array voltage, but can also Continue reading
The number of vehicles has increased significantly in recent years, which causes high density in traffic and further problems like accidents and road congestions. A solution regarding to this problem is Continue reading
A high level model of HSIPHY mode of IEEE 802.15.3c standard has been constructed in Matlab to optimize the wordlength to achieve a specific Continue reading
To implement a utility wireless sensor network, investigation of different wireless protocols has been performed. The protocols are Bluetooth, Wi-Fi, IEEE 802.15.4 and Continue reading
Business-information systems (IS) alignment has become an important strategic imperative for organizations competing in the global economy. Recent research indicates that Continue reading
This paper presents a novel algorithm for computing absolute space representations (ASRs) for mobile robots equipped with sonar sensors and an odometer. The robot is allowed to wander freely (i.e. without following any fixed path) along the corridors in an office environment from a given start point to Continue reading
Mobile WiMAX (Worldwide Interoperability for Microwave Access) or 802.16e standard was ratified by the IEEE in late 2005 as a potential to emerge as a real viable competitor to existing 3G technologies.
Mobile WiMAX uses an OFDMA™ technology called Continue reading
Owing to the usage of Internet, concerns about protecting and enforcing intellectual property (IP) rights of the digital content are mounting. Unauthorized replication and manipulation of digital content is relatively easy and can be achieved with inexpensive tools.
Digital rights management (DRM) systems address issues related to ownership rights of digital content. Various aspects of content management – namely, Continue reading
Human-computer interaction has become an increasingly important part of our daily lives. The movement of user’s eyes can provide a convenient, natural and high-bandwidth source of input. By tracking the direction of gaze of the user, the bandwidth of communication from the user to the computer can be increased by Continue reading
This paper proposes a novel evolutionary approach to spreading code design in direct sequence code division multiple access (DS-CDMA). Specifically, a multiobjective evolutionary algorithm (EA) is used to generate complex spreading sequences that are optimized with respect to the Continue reading
In this project, you can learn how robotic technology can improve the lives of people with disabilities to help them pick everyday objects. In the laboratory, Lego Mindstorms NXT kits are used to create an artificial arm or hand that can lift small objects, such as a coffee cup. Continue reading
