Discussion Session
During Friday lecture every 3rd week, starting in the 5th week of the semester. In the discussion session we will review basics, investigate material covered in class from a different perspective, answer questions, and discuss recent developments in the field.
Homework
Homework assignments are given every week, starting in the 2nd week of the semester. Each problem set is due one week after it has been handed out.
Homework Submission
Homeworks will be submitted electronically, as pdfs. Homeworks may be prepared by hand, in LaTeX, or even using Microsoft Word. If by hand the homework need to be scanned to pdf. Note that student will need to name file "Name_hwX.pdf" (e.g. second homework file "Arun_hw2.pdf") in order to submit it.
Grading
Homework: 0%, Quizzes: 10%, Mid Semester Exam: 40% (20% each), End Semester Exam: 50%
Course Details
Objectives
- To provide students an understanding of the concepts related to transmission and reception techniques for communications.
- To provide communication concepts and techniques required for implementation of a digital communication transceiver and application of these concepts in a system context.
- To provide concepts and techniques required for holistic understanding of a communication system. The concepts taught in class will be discussed in the context of wired telephony, cellular communication systems, satellite communications, and deep space communications.
Learning Outcomes
- Ability to analyze and design basic communications systems.
- Ability to apply concepts and techniques from communication theory to design communication systems.
- Develop the ability to compare and contrast the strengths and weaknesses of various communication techniques for various channel types.
Pre-requisites
Probability theory with emphasis on Gaussian random process; signal space concepts; linear algebra
