Abstract
LEO is Low Earth Orbit satellite.It circulates on a lower orbit in a shorter period . Additionally LEO systems try to ensure a high elevation for every spot of the earth to provide a highquality communication page link . The networks will play an important role in the evolving information infrastructure . It provides communication with shorter endto- end delays and e_ciency frequency usages . Some problems need to be solved before LEO satellite system can be successfully deployed . One of these problems is handover management . Even ....etc

A/D and D/A Conversion,analog to digital and digital to analog


Data Converter impacts the factor for the performance of the overall radio design
Requirements: very high sampling rates, high number of effective quantization bits, an operating bandwidth of several Ghz, a large spurious-free dynamic range, a reasonable price
DAC and ADC converters
Sampling and Quantization
Nyquist Zones
Aliasing
Bandpass filtering – uses image to translate bandpass signals to baseband
Errors occurs in Quantization

Abstract:

Digital audio broadcasting, DAB, is the most fundamental advancement in radio technology since that introduction of FM stereo radio. It gives listeners interference - free reception of CD quality sound, easy to use radios, and the potential for wider listening choice through many additional stations and services.

DAB is a reliable multi service digital broadcasting system for reception by mobile, portable and fixed receivers with a simple, non-directional antenna. It can be operated at any frequency from 30 MHz ....etc

Satellite digital radio is a radio system, which is specially designed for car radios. The operation of the satellite digital radio is that satellite receives the data generated by uplink station, amplify this data and send it back through special spot beam not only to fixed but also to mobile and portable receivers. complementary terrestrial transmitter may be necessary, because in big cities high rise buildings may block the signals from the satellites. In this seminars, an attempt is made to explain the different existing satellite systems ....etc

Digital-to-Analog Analog-to-Digital
Data Handling Systems
Both data about the physical world and control signals sent to interact with the physical world are typically analog or continuously varying quantities.
In order to use the power of digital electronics, one must convert from analog to digital form on the experimental measurement end and convert from digital to analog form on the control or output end of a laboratory system.
Digital-to-Analog Conversion
When data is in binary form, the 0's and 1's may be of s ....etc

ABSTRACT

This paper presents a new design and implementation of HDD (Hard Disk Drive) embedded DSR (Digital Satellite Receiver). The digital broadcasting technology enables multimedia access via broadcasting system. The amount of digital data to be processed is increased as compared to the previous broadcasting environment. In this paperâ„¢ a method is proposed to provide storage ability of a DSR to cope with these changes. Efficient digital data storage and management technology is also discussed. The real data recording and playing b ....etc
