Textbook

Lathi, B., Modern Digital & Analog Communication Systems, 3rd Ed., 1998

Course Description

This course introduces and emphasizes essential analytical tools and theories of communication systems. Knowledge of Fourier series, transforms, and transmission of signal through linear systems is fundamental for this course. Analog communications, such as Amplitude Modulation and Angle Modulation (FM, PM), are major parts of this course. Sampling theorem and quantization are also covered followed by an introduction to digital communications, line coders, and pulse shaping.

Course Objectives

The course objectives are to enable the students to:

  1. Understand the fundamental concepts of communication systems.
  2. Understand and compare several analog modulation schemes.
  3. Apply sampling and quantization theorems to convert analog signals to digital.
  4. Design basic communications systems, FDMA and TDMA.
  5. Enhancing group work through a course project.
