ABSTRACT
Satellite crosslinks generally require narrower bandwidths for increased power concentration. We can increase the power concentration by increasing the cross page link frequency with the same size antenna. But the source technology and the modulation hardware required at these higher frequency bands are still in the development stage. Use of optical frequencies will help to overcome this problem with the availability of feasible light sources and the existence of eff ....etc

Free space optical communications is a line-of-sight (LOS) technology that transmits a modulated beam of visible or infrared light through the atmosphere for broadband communications. In a manner similar to fiber optical communications, free space optics uses a light emitting diode (LED) or laser (light amplification by stimulated emission of radiation) point source for data transmission. However, in free space optics, an energy beam is collimated and transmitted t ....etc

Abstract
Most device drivers have one ulterior motive and one target to achieve - deliver the maximum using the minimum. No matter how stable or feature rich a device driver might be, if it cannot perform in terms of high throughput and low CPU utilization, it is as good as any other run of the mill driver.The objective of this topic is to use the thinking out of the box concept and expose techniques, which go beyond just good programming principles to get that extra edge which can put your next driver into the elite group of high perform ....etc

Abstract:

In this paper, analysis of CDMA network with Optical Amplifiers has been done. As the optical amplifier provides gain as well as has nonlinear characterstics, gain is expected due to signal amplification as well as operation of SOAs as limiter due to gain saturation. In this paper results have been computed for with different SOA placements in a typical star topology employing CDMA. The results show that in a star topology network employing CDMA, placement of SOAs before CDMA decoder does provide benefit due to g ....etc

INTRODUCTION
Explosive information demand in the internet world is creating enormous needs for capacity expansion in next generation telecommunication networks. It is expected that the data- oriented network traffic will double every year. Optical networks are widely regarded as the ultimate solution to the bandwidth needs of future communication systems. Optical fiber links deployed between nodes are capable to carry terabits of information but the electronic switching at the nodes limit th ....etc

CHAPTER 1
INTRODUCTION

Communication links between space crafts is an important element of space infrastructure, particularly where such links allow a major reduction in the number of earth stations needed to service the system. An example of an inter orbit page link for relaying data from LEO space craft to ground is shown in the figure below
