Computer engineering (Academic Year 2014/2015) - Information and communication technologies engineering (reserved for the students of Helwan University, Cairo, Egypt)

Communication technologies


Credits: 12
Content language:Arabic
Course description
The course aims to treat the basic elements of telecommunications. Starting from the signals theory, it will be processed the main concepts of telecommunications theory . Particularly we will study the techniques of transmission and reception of various types of channels: electrical cables, radio channels and optical fibers
Prerequisites
calculation and linear algebra
Program
Introduction to the theory of signals: deterministic Signals, Fourier transform, spectral analysis, definition of a signal band of, the transfer function and definition of bandwidth of a system, filters. Sampling theorem. Random signals, statistical characterization and hints on the power spectrum. Analog & Digital transmissions: Analog Sources, analog modulations (AM, FM). Digital transmissions: Sources numbers, quantization, PCM conversion and A / D and D / A. Digital modulations (ASK, PSK, FSK, QAM).
Exercises
Exam will include three main points: one exercise and two Open questions Exercises will concern above all: -Convolution and Correlation exercises between known signal forms. -Fourier Transform method -TLC systems and filters To improve Exam simulation, it is suggested to try to break Convolution and Correlation exercises in three steps, aimed to: -to graph or describe signal in analytic -to perform the calc, trying the calculation way or the visual way (generally faster). -to graph results Exam will concern theory test. It is suggested to focus on Digital Transmission and analog modulations
