Abstract

Comparative studies on DWT-OFDM and FFTOFDM systems are presented. The model for DWT-OFDM includes zero-padding and vector transpose for transmitting the OFDM signal. MATLAB simulation commands are also described. The discrete wavelet transform-OFDM (DWT-OFDM) has to satisfy the orthonormal bases and the perfect reconstruction properties to be considered as wavelet transform. Different wavelet families have been used and compared with the conventional F ....etc

Abstract Even though their capacities are still orders of mag- nitude lower than those of hard disks, flash storage sys- tems are rapidly gaining importance in energy-constrained systems. This paper focuses on USB flash drives, which can provide portable storage to mobile systems or stor- age to systems that otherwise do not have persistent stor- age opportunities (e.g., low-power sensor devices). The paper presents studies relating to power consumption, en- ergy overheads and benefits, and performance impacts of USB flash drives. The key insig ....etc

Under the Guidance of
Mr. Pradeep Kumar Jena.



abstract

Flash memory is erased in sections whose sizes and locations in the chip are defined by the part s manufacturer.
As a result, once a flash memory location is programmed, the entire section containing the location must be erased before that location can be programmed again. ....etc

lightning arrester
A lightning arrester is a device used on electrical power systems and telecommunications systems to protect the insulation and conductors of the system from the damaging effects of lightning. The typical lightning arrester has a high-voltage terminal and a ground terminal. When a lightning surge (or switching surge, which is very similar) travels along the power line to the arrester, the current from the surge is diverted through the arrestor, in most cases to earth.
In telegraphy and telephony, a lightning arrestor is plac ....etc

working of igbt with flash animation

What is an IGBT?
An IGBT, or insulated gate bipolar transistor, is a solid state device (with no moving parts). It is a switch that is used in order to allow power flow in the On state and to stop power flow when it is in the Off state. An IGBT works by applying voltage to a semiconductor component, therefore changing its properties to block or create an electrical path.
Types of IGBTs

There are many different kinds of IGBTs. At Future Electronics we stock many of the most common types categorized by Turn- ....etc

A flash mob computing (also flash mob computer) is a temporary ad-hoc computer cluster running specific software to coordinate the individual computers into one single supercomputer. A flash mob computer is distinct from other types of computer clusters in that it is set up and broken down on the same day or during a similar brief amount of time and involves many independent owners of computers coming together at a central physical location to work on a specific problem and/or social event. Flash mob computer derives its name from the more gene ....etc

Abstract

The demand for high-speed mobile wireless communications is rapidly growing.
OFDM technology promises to be a key technique for achieving the high data capacity and spectral efficiency requirements for wireless communication systems of the near future. This work presents an investigation into methods for maximizing the spectral efficiency of Orthogonal Frequency Division Multiplexing (OFDM) systems. The current standards such as IEE 802.11a in USA and H ....etc
