Course Content

Review of EE229 and EE325: Fourier transform random processes Lowpass representation of bandpass signals and systems: downconversion and upconversion, lowpass representation of bandpass systems Analog modulation techniques: Amplitude modulation, DSB, SSB, VSB modulations, Angle modulation: FM and PM Sampling, quantization and pulse modulation: Sampling and pulse amplitude modulation, PCM and DPCM, Delta modulation, scalar and vector quantization Overview of multiplexing and multiple access techniques: TDM(A), CDMA, FDM and OFDM(A) Digital modulation techniques: Basics of PSK, ASK, FSK, QAM; ML demodulator implementation with matched filter, decision regions and probability of error analysis. Digital communication over bandlimited channels: Intersymbol interference, Nyquist criterion for ISI-free pulse, raised cosine pulse, ML sequence detection for bandlimited channels.

Feedback on Lectures

The course ran in an online mode with recorded lectures. The videos provided by Prof Shabbir Merchant were from previously recorded CDEEP lectures. These lectures were very good with hand-drawn and handwritten explanations in the video by the professor. The lectures videos by Prof Kasbekar were a bit dry and difficult to understand in comparison and were mostly a repetition of the written content of slides shown in the video.

Feedback on Evaluations

Best ⅔ quizzes for 20% Midsem for 30% Endsem for 50% All of them were subjective and required some thinking and application. Solving the provided practice problem sets (including questions from the reference books) helped a lot in the exams.
