Course Objectives For students to:
  1. Understand how to model, analyze, and design the deterministic signal generation and processing aspects of analog and digital communication systems.
  2. Understand the need to use probability theory and random processes to design and analyze real-world communication systems and to predict their performance in the presence of noise and interference.
  3. Prepare for more advanced communications courses covering topics such as advanced modulation, demodulation and channel modelling methods, data networking, information theory, and secrecy and error control coding.
Learning Outcomes After taking this course students will be able to recognize and use the following concepts, ideas, and/or tools:
  1. Baseband signaling, including pulse amplitude modulation (PAM), partial response signaling, sampling, bandwidth requirements, and extraction of timing signals.
  2. Bandpass signaling, including amplitude, phase, frequency modulation (AM, PM, FM), carrier synchronization, complex baseband representation of real bandpass signals, amplitude, phase, frequency shift keying (ASK, PSK, FSK), quadrature amplitude modulation (QAM), signal constellations, orthogonal frequency-division multiplexing (OFDM), and spread spectrum communications.
  3. Communications in the presence of noise and interference, real and complex valued noise signals, matched filters, intersymbol interference (ISI), probability of symbol errors, and error control coding.
