ABSTRACT :Huge demand for new services in cellular systems led engineers and professionals to improve networks and magnetisms to achieve people needs and improve their work.
UMTS is one of the most important steps in cellular systems that motivate us to study its concepts and characteristic and try to simulate them by Matlab GUIs.
In our project we focus on the characteristics of the UMTS and the most important cosepts that differ from second generation of mobile system which is CDMA, HANDOVER and POWER CONTROLE

ABSTRACT : The purpose of this project is to simulate and design the circuits of an Instrument Landing System ILS “marker beacons”. This will give the ability to determine the position of a landing aircraft during Instrument Meteorological Conditions (IMC),such as reduced visibility due to fog, rain, or blowing snow to enable a safe landing to an aircraft approaching a runway. The position is given by three markers which are located on the ground with a specified distance before the threshold of the runway (according to application of the airport).
This project contains modulation, demodulation, power circuits, antenna, and a micro-controller for coding/decoding according to each marker.

ABSTRACT : The purpose of our project is to designed and implement a wireless optical transmitter and receiver system that established a data and audio communication, In addition, this project also proposed laser communication at certain angle which is a new solution or techniques to undertaken the characteristic of light that propagates in a straight line although the signal is very low or weak over long distance. The light communication system can work successfully within in distance up to 10 meters and sensitivity angle of the photodiode at receiver that view the laser light coming from the transmitter so this project have three topics to be implemented “data which is digital signal, voice which is analog signals, alignment angle and acceptance angle” .
The project has a lot of application may be developed such as military apps and civil apps which use the free space and direct light to be spared.
This project is successfully improved the transmission distance and signal coverage area effectively with low cost of hardware.

ABSTRACT: The purpose of this project is to develop and implement an application that simulates an FM System using C# Programming Language. The application works as a visual aid, and gives the ability to generate three types of input signals with ability to control their parameters (Frequency and Amplitude). The application can also generate a carrier signal ranged at the FM standard band of frequencies (88 to 108 MHz). The main task of the application arises when frequency modulate the carrier signal with respect to the message signal which is already generated (three types). Then, the modulated signal is transmitted over a channel and affected by channel noise–where the user can vary its parameters-.Detecting and recovering the message signal at the receiver end is also a possible process in the application. All the generated signals and the modifications applied to them are displayed on dedicated windows.

ABSTRACT :Phase shifters are four-port microwave devices which take an input signal and output in phase and shifted phase version of the original signal. These devices can be used in phased antenna arrays, balanced mixer, and Amplifier. The goal of this work is to construct a hybrid coupler phase shifter which will provide a 90 degree phase shift to a signal with a center frequency of 2 GHz over a 200 MHz bandwidth.
What made this project exceptional is the hybrid coupler phase shifter has not been extensively studied. Some papers have provided rough guidelines for constructing these shifters, but there is little exploration of performance.
This work uses AWR as a simulation tool to provide design analysis, and experimental work was performed in the RF laboratory at the Arab International University “AIU
