details regarding the course.
Course No. : ECE F311 / EEE F311

Course Title : Communication Systems
Instructor-in-Charge : Prof. Pranay Agarwal
Course Description:
Analysis and design of communication systems; analog and digital modulation and demodulation, frequency conversion,
multiplexing, noise and distortion; spectral and signal-to-noise ratio analysis, probability of error in digital systems, spread
spectrum. Introduction to the basic principles of the design and analysis of modern digital communication systems. Topics
include source coding, channel coding, baseband and passband modulation techniques, receiver design, and channel
equalization.
Scope and Objective of the Course:
This course intends to cover the basic understanding of functionalities of various block-sets involved in communication
system. The topics like Analog to Digital conversion, Pulse coding, Modulation (Analog and Digital, Baseband and
Bandpass), source coding, channel coding, Multiple access, Multiplexing techniques, Spread spectrum will be covered
with appropriate detail and mathematical description. Important topic like Information theory and its fundamental limits
will be emphasized to appreciate the concepts of digital communication. Students will be introduced to the functioning of
modern communication systems and how they perform in the presence of noise. Students will be given assignments on
communication system modeling using MATLAB. The laboratory component involves system design and simulation
exercises using MATLAB and Simulink and experiments based on HW boards. Advance/application areas like wireless,
optical, satellite, acoustic communication will be covered towards the end. Students are expected to have sound
understanding of Signals and systems, Mathematics, Electromagnetic Field theory
