ABSTRACT

OFDM (Orthogonal Frequency Division Multiplexing) is a modulation and multiple access technique that has been explored for over 20 years. Only recently has it been finding its way into commercial communications systems. OFDM, or multitone modulation, is presently used in a number of commercial wired and wireless applications. In order for any mobile system to create a rich user experience, it must provide ubiquitous, fast and user-friendly connectivity. OFDM has several unique properties that make it especially well suited to handle ....etc

Introduction


PROFILE OF PONLAIT ORGANIZATION
Pon – Pondicherry
Lait - Milk
The Pondicherry Co-operative Milk Producer’s Union had its origin as the Pondicherry co-operative milk supply society during the year 1955. The supply society had 50 individuals’ members on its rolls. The union was the first co-operative society was registered in Pondicherry. It still maintains its prominence amongst the co-operative societies in Pondicherry and it is the Apex co-operative society.

ABSTRACT:

OFDM
otherwise called orthogonal frequency division multiplexing is a modulation and a multiple access technique that can be applied to mobile communications.
OFDM or Multitone modulation as it is sometimes called is the basis for several commercial wireless applications. In OFDM the segments are according to frequency there by dividing the spectrum into a number of equally spaced tones, which are orthogonal with each other and carries a portion of user information ....etc

ABSTRACT
Orthogonal frequency Division Multiplexing (OFDM) is
multicarrier transmission technique. OFDM is a communication technique
that divides the communication channel into a number of equally spaced
frequency bands. A sub carriers a portion of the users information in
each band. Each sub carriers is orthogonal (Independent of each other)
with every other sub carrier. OFDM efficiently squeezes multiple
modulated carriers tightly together reducing the required bandwidth.
OFDM was invested in 1960â„ ....etc

Abstract
The symbolic database system is the basic tool of geospatial data representation in map. In the past, many researchers didn’t focus on 3D map symbols but mostly on 2D map symbols. In 3D GIS, all geographic phenomena and spatial entities need to be represented by the corresponding 3D symbol models. So establishing a complete set of 3D map symbolic database with expression becomes critical in technology development of 3D map visualization. Based on the theory of map information transmission, the categorical ....etc

Title: cognitive radio systems

Abstract

Efficient use of radio spectrum is a necessity for future wireless systems. While the vast majority of the frequency spectrum is licensed to different organizations, observations provide evidence that usage of the licensed spectrum is by far not complete

neither in the time domain nor the spatial domain. This material discusses basics of Cognitive radio (CR), classifications of

cognitive radio systems, cognitive system architecture, antenna design for cognitive radio system.

ABSTRACT
Data compression is the technique of converting an input data stream or the original data into another data stream which is shorter in length. There are many known methods for data compression. They are based on different ideas and are suitable for different types of data. But they all have the same principle that they compress data by removing the redundancy in the original data. Otherwise data compression can be looked up on as a change in representation from inefficient to efficient form.
