Abstract
There are new system implementation challenges involved in the design of cognitive radios, which have both the ability to sense the spectral environment and the flexibility to adapt transmission parameters to maximize system capacity while co-existing with legacy wireless networks. The critical design problem is the need to process multi-gigahertz wide bandwidth and reliably detect presence of primary users. This places severe requirements on sensitivity, linearity, and dynamic range of the circuitry in the RF front-e ....etc

 INTRIDUCTION TO BROAD BAND
Broadband is a faster way for you to gain access to the Internet and the sites or pages that you want to see. Broadband Internet offers high- speed Internet access - high speed in terms of data transmission, upload, and download times, and connectivity. If you compare broadband Internet with a regular dial-up connection, you certainly won’t like going back to the latter.

Electrical Engineering Department, College of Signals, National University of Science & Technology, Pakistan


Abstract—

Cognitive networks can potentially solve the
problems of spectrum scarcity by accommodating unlicensed
(secondary) users in under-utilized segments of the spectrum.
Spectrum sensing serves as the primary stimulus for a cognitive
radio an ....etc

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

Summary
The project mainly describes about the technical aspects of integrated navigation radio (INR). This type of Navigational System is first introduced in B-787 where many components such as VOR, MB, MMR combined in the Integrated Navigation Radio. Firstly the project mainly gives a brief description about the radio navigation system used in B-777 and B-787 as both the aircrafts are long range and fuel efficient aircrafts. The project also states the use of data buses in the system. It also clearly aims that due ....etc

ABSTRACT
Satellites are one of the greatest achievements of mankind. They have been used for various applications like communication, military application, weather forecasting and so on. They play a big role in the case of television channels and other entertainment networks. One of the latest applications of satellites is the satellite radio.

Satellite radio is a subscriber based radio service that broadcast directly from satellites. It is an advanced form of mobile radio service where one can rec ....etc

ADVANCEMENTS IN MOBILE TECHNOLOGY
ABSTRACT:
The pace of technological advances is so fast that the communication devices become obsolete within just few years of their production. To keep up with this pace, communications systems must be designed to maximize the transparent insertion of new technologies at virtually every phase of their lifecycles. When these new technologies are inserted, the upgraded devices should still be able to communicate with each other.
The term Software ....etc

ABSTRACT
UWB is a wireless technology that transmits binary data”the 0s and 1s that are the digital building blocks of modern information systems. It uses low-energy and extremely short duration (in the order of pico seconds) impulses or bursts of RF (radio frequency) energy over a wide spectrum of frequencies, to transmit data over short to medium distances, say about 15”100 m. It doesn™t use carrier wave to transmit data.
