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

Sensor networks are widely being used for sense-response applications. The role of the sensor nodes in such applications is to monitor an area for events of interest and report the occurrence of the event to the base-station. The receipt of the event at the base-station is followed by a prompt physical response. An example of a sense-response application is the detection of fires in a forest. The sensor nodes report the occurrence of a fire upon which fire trucks are immediately dispatched to the location of the fire. Other examples of sense-re ....etc

Abstract

A response surface model of the luminous flame emissivity of sodium pool fire has been proposed for use in safety analysis computer codes of a liquid metal fast reactor. The liquid sodium burns in air resulting in not only heat generation but also release of sodium oxide aerosols of sub-micron diameters. Aerosols levitating in air are radiative and they influence the allocation of combustion heat from the flame to atmospheric gas or sodium pool. The emissivity of the flame needs to be quantified, as it is one of user-specified param ....etc

Abstract
Monitoring the health of power transformer is important for the reliability of electrical power supply. Conventional tests carried out on power transformers can only detect damage of permanent nature. Frequency Response Analysis (FRA) is found to be a useful tool for reliable detection of incipient mechanical fault in a transformer. There are various methods of evaluating the frequency spectrum to confirm the presence ....etc

Interactive Voice Response System (IVRS) is one of the most important breaks through in the field of telecommunication. IVRS provide a voice response to the customers and guide them to the information they require. The customers can call up any institute such as banks, universities, tourism industry and obtain any information by simply pressing certain button on his telephone as per the guidance of the voice fed into the computer.IVRS is an electronic device through which information is available related to any topic. IVRS is usually employed ....etc
