Aims
The aim of this course is providing the basic tools for understanding, analyzing, designing and simulating a communication system.
Students will be able to list different transmission media and they can perform a basic link budget calculations for a wireless communication system 
Students will be able to analyze/design simple modulator and demodulator for analog and digital modulation schemes, analyze their spectral characteristics 
Students can mathematically analyze the basic communication systems in the presence of noise
Students can analyze and perform calculations using the basic concepts of stochastic processes which are required in understanding and analysis of communication systems Students will be able to model modulator/demodulator and the behavior of a basic communication system in presence of white noise using MATLAB.
Content
Overview on different types of transmission media including free space for wireless and basics of wireless link budget calculations
Analog modulations (FM and AM), modulator and demodulator structure, different types of modulation (DSB-FC, DSB-SC,…) and their spectral characteristics 
Baseband signals and transmission, signal space representation, complex baseband representation of passband signal and digital baseband transmission for bandlimited channels. 
Digital modulation schemes (PSK, ASK, FSK) and their characteristics from bandwidth efficiency, power efficiency and complexity perspective.
Analysis of modulation schemes in the presence of Gaussian noise, optimum receiver design for AWGN channel and error probability calculations.
Random processes definition and related concepts including ACF, stationarity, ergodicity, narrowband noise (and its effect on error performance calculation) and power spectral density.
Thermal noise and its equivalent circuits, noise figure and equivalent noise temperature.

Tests consist of three written tests (Test1, Test2, and Test3). The grades of all tests >=5. There are three pass/fail labs and one pass/fail project. 
If 3 labs and the project have been passed, the final grade is 0.5*Test1+0.2*Test2+0.3Test3. If final grade >=6, a bonus between 0 and 1 can be added to the final grade. It depends on completion of all steps of the project and the quality of the project.

NB. If you want to follow the old 4EC version of COM, please contact the module coordinator as soon as possible discuss to a specific arrangement. In this 6EC version COM, topics have been added with respect to the 4EC version. You cannot take the 6EC version as a replacement of the 4EC version.
