This course provides students with a thorough understanding of the fundamental principles that govern the reliable transmission of digital data over noise-corrupted and bandwidth-limited waveform channels. It starts with a tutorial introduction to the basic elements of communication systems, covers basic principles of baseband transmission of signals, and includes a review of stochastic processes. The focus of this course lies on digital modulation techniques (PAM, PSK, QAM, FSK, CPM, GMSK), the design of optimum receivers, and performance evaluation of these receivers. The course also includes an introduction to multiplexing techniques (FDM, TDM, CDM), and elements of source and channel coding.
While there will be many examples given to illustrate the practical relevance of the methods introduced, this course is mathematical in nature. Students will develop confidence in their ability to solve mathematical problems of analysis and design. Many of their timeless insights and intuitions about communications will be drawn from this course.

1. Elements of communication systems.
2. Baseband transmission of signals: impulse shapes, Nyquist conditions, partial response.
3. Representation of communication signals: analytic and equivalent lowpass signals, signal space representation.
4. Review of random processes, including stationarity, ergodicity, power spectral density, linear systems with random imputs.
5. Important digital modulation techniques: linear (PAM, PSK, QAM, FSK) and nonlinear (CPM, GMSK), spectral characteristics.
6. Optimum receivers (coherent and noncoherent) for the AWGN channel and performance evaluation in terms of bit error rate and bandwidth efficiency.
7. Introduction to multiplexing techniques: FDM, TDM, CDM.
8. Elements of source coding and error control coding.
