Course Rationale and Goals
The course is planned as a senior-level ‘Technical Elective’ course. It assumes that the students have a background in signals and systems, frequency domain spectrum, probability and statistics. The course presents the fundamentals of digital communication systems and evaluates the performance of digital signaling on physical channels.
Topic 2Introduction to binary modulated bandpass signaling techniques:
Binary On-off Keying (OOK), Phase-shift Keying (BPSK) and Frequency-shift Keying (FSK) techniques will be introduced and examined
Topic 3Multilevel modulated bandpass signaling schemes:
Quadrature Phase-shift Keying (QPSK), M-ary Phase-shift Keying (MPSK) and Quadrature Amplitude Modulation (QAM) techniques will be introduced and examined
Topic 4Review of probability and random variables:
Review of probability theory, random variables, probability density functions, ensemble averages, distributions and functional transformation of random variables.
Topic 5Random processes and the representation of the random noise:
Random processes, stationarity and ergodicity, correlation functions, power spectral density, Wiener-Khintchine Theorem, white noise, bandpass processes
Topic 6Matched filter receivers:
Matched filters in white noise. Integrate-and-dump and correlation realizations of the matched filter.
Topic 7Error probabilities for baseband signalling:
- Error probabilities of polar unipolar signaling in white Gaussian noise
Topic 8Detection and error probability for bandpass signals
- Probability or error analysis for bandpass signaling employing coherent and noncoherent detection.
Topic 9Comparison of digital signaling systems:
- Comparison of digital signaling schemes in terms of probability of error, bandwidth and power requirements
