The aim of this course is to help the reader to understand the concepts of communication systems include modulation/demodulation techniques in both analogue communications (in details) and digital communications (brief review). In addition to that, pulse modulation and baseband data transmissions are studied. For this purpose, analysis of deterministic signals in frequency domain are reviewed. Furthermore, noise in communication systems, white noise and noise band-width are presented. For this purpose, a brief review of random variables and stochastic processes are introduced. The syllabus of the course is as follows.
- Short description of an analog communication system
- Fourier analysis of deterministic signals
- Amplitude modulation (AM, DSB-SC, SSB, VSB)
- Angular modulation (FM and PM)
- Review of random variables, stochastic processes, white noise
- Calculation of signal to noise ratio (SNR) in amplitude/angular modulations
- Pulse modulations
- Baseband data transmission (introduce inter symbol interference)
- Introduction of digital communications (BASK, BPSK, BFSK, QPSK, M-ary digital modulations)
