A NEW PARALLEL INTERFERENCE CANCELLATION ALGORITHM FOR RAKE SYSTEMS
In order to suppres the multi-path interference (MPI) in the DS CDMA system, a new RAKE receiver based on parallel interference elimination is first proposed in this paper data symbol tentative decision is obtained by linear decision; the multi-path interference are evaluated by tentative decision and known user information. Then the performance over Rayleigh fading channel are analyzed and compared to conventional parallel interference cancellation (PIC) and RAKE receiver. It is shown that RAKE receiver performance can be improved greatly by using this method with simple structure and easy implementation
Reconfigurable Computing: innovative technology for scientific community
43 p.Reconfigurable Computing marks a revolutionary and hot topic that bridges the
gap between the separate worlds of hardware and software design. The key feature
of reconfigurable computing is its groundbreaking ability to perform computations
in hardware to increase performance while retaining the flexibility of a software
solution. Reconfigurable computers serve as affordable, fast, and accurate tools for
developing designs ranging from single chip architectures to multi-chip and
embedded systems. Given the architecture and design flexibility, reconfigurable
computing has catalyzed the progress in hardware-software code sign technology
and a vast number of application areas such as scientific computing, biological
computing, artificial intelligence, signal processing, security computing and
control oriented design. We give an overview of the hardware architectures of
reconfigurable computing machines, and the software that targets these machines,
such as compilation tools. Also, we consider the issues involved in run-time
reconfigurable systems, which re-use the configurable hardware during program
executio
DESIGN AND IMPLEMENTATION OF LOW POWER PULSE TRIGGERED FLIP FLOP BASED ON SINGLE FEED THROUGH METHOD
The low law has turned into a predominant thought in today’s televisions production. Over prehistory decemvirate, the prestige decrease of VLSI markers has at all times been developing. In Integrated Circuit, there's a shortage of information to be in contact in association with good judgment fences the use of U-turn (FF). In an FF, an enormous section of one's on-chip law is fed on by turnip arrangements, which is composed of determining elements corresponding to FFs, latches and alarm placement net. These components exhaust 30% to 60% of one's budget sovereignty inside an arrangement. So to cut back Power disintegration, more than a few typical approaches are implemented the use of TSPC but there's a discharging avenue headache. To shrink aspire discharging, a range of purposes happen to be implemented. The real beckon satisfies straight strategy is implemented to decrease discharging trouble, but pitfalls to a new go computers attributable to its unambiguous charging and discharging. Another fault is over the variety of transistors recycled and management decrease is again rich. The suggested Low Power Pulse-Triggered Flip-Flop Design amidst Conditional Pulse Enhanced Technique overcomes the ache discharging street trouble. This mode encloses catch computers common sense (PTL) primarily based AND port and additional go transistors recycled at sundial technique. The results demonstrated based mostly on place blueprint simulation the use of Tanner Software CMOS 45nm telecommunications. The planned manner improves strength expenditure and delay
Embedded system: enhancement of performance with new challenges and solutions
Due to the rapid development of electronic technology and requirements of
electronic markets, electronic products tend to become smaller, faster, and more
popular. Embedded systems have become increasingly widespread in many areas
including industrial areas and our daily life. Their extensive use and integration in
everyday products marks a significant evolution in information science and
technology. A main trend is the proliferation of embedded systems that should
work in seamless interaction while respecting real-world constraints. Technology
advances and a growing field of applications have been a constant driving factor
for embedded systems over the past years. However, the increasing complexity of
embedded systems and the emerging trend to interconnections between them lead
to new challenges. Intelligent solutions are necessary to solve these challenges and
to provide reliable and secure systems to the customer under a strict time and
financial budget. In this paper details the overview of the technology trends,
reasons of significant change in application implementation philosophy, outlines
new challenges, issues and finally presents a methodology to deal with solution

LOW ALTITUDE AIRSHIPS FOR SEAMLESS MOBILE COMMUNICATION IN AIR TRAVEL
The Aviation Administration policy prohibits the use of mobile phones in Aircraft during transition for the reason it may harm their communication system due to Electromagnetic interference. In case the user wants to access cellular network at higher altitudes, base station
access is a problem. Large number of channels are allocated to a single user moving at high speed by various Base Stations in the vicinity to service the request requiring more resources. Low Altitude Platforms (LAPs) are provided in the form of Base stations in the Airships with antennas projected upwards which has direct link with the Ground Station. LAPs using LongEndurance
Multi-Intelligence Vehicle (LEMVs) equipped with an engine for mobility and stable positioning against rough winds are utilized. This paper proposes a system that allows the passengers to use their mobiles in Aircraft using LAPs as an intermediate system between
Aircraft and Ground station. As the Aircraft is dynamic, it has to change its link frequently with the Airships, MANETs using AODV protocol is established in the prototype using NS2 to provide the service and the results are encouraging
ESTIMATION OF SEISMIC RESPONSE OF SYMMETRIC & ASYMMETRIC MULTISTOREED BUILDING
Structures might be thought about as crooked in strategy or in altitude based upon the circulation of mass as well as rigidity along each floor, throughout the elevation of the structures. A lot of the uneven areas of India are very seismic. A structure on hillside incline varies in various methods from various other structures. In this research, 3D logical version of 4 and also 9 fabled structures have actually been produced for symmetrical and also uneven structure versions as well as assessed utilizing architectural evaluation device "ETABS Nonlinear". To research the impact of differing elevation of columns in ground floor as a result of sloping ground, the strategy format is maintained comparable for both structures on airplane and also sloping ground. The logical design of the structure consists of very important elements that affect the mass, stamina, rigidity as well as deformability of the framework. To examine the impact of infill throughout quake, seismic evaluation making use of both straight characteristics (action range technique) in addition to nonlinear fixed treatment (piece of cake) has actually been executed
