This course presents an introduction to analog and digital communication systems. The main topics are: a review of the Fourier transform; representations of bandpass signals; random signals in communications, including stationarity, ergodicity, correlation, power spectra and noise; amplitude and frequency modulation; frequency division multiplexing; baseband digital communication; time division multiplexing; and an introduction to basic digital modulation schemes, such as BPSK, FSK and QPSK.
Probability theory and linear system courses are the required prerequisites for this course. You will also be expected to be able to program in MATLAB.

There will be no class on 6th, 8th and 13th of December. The make-up lecture (pre-recorded) is now available at ICampus.
Please send me any questions regarding the lecture by email.
The final exam will be taken on Thursday, December 15, 16:30 to 18:30, in room 22003.
You will be allowed to bring one sheet of notes (both sides fine) into the exam along with calculators.
The following topics will be tested in your final exam:
1) Angle modulation (complex envelope, signal bandwidth and spectrum analysis, phase/frequency deviation) (Notes #8, 9,10)
2) Wideband FM generation via indirect method (Note #11)
3) FM demodulation via discriminator (Note #12)
4) FM demodulation via PLL (Note #13)
5) Random process, correlation and power spectral density, and narrowband noise (Notes # 19, 20, 22, 23)
6) SNR analysis for DSB/AM/SSB and FM (Notes #24, 25)
Please practice the old exam posted on the handout section.
