Elementary Number Theory with Applications to Communication Systems
The course is divided into two parts. In part one, students are introduced to the fundamentals of number theory. This includes: Representation of integers to different basis, Fundamental theory of arithmetic, Linear and higher order congruences and their applications, Euler phi-function and its importance, Primitive Root definition, as well as Quadratic Residues and Legendre symbol.
In the second part of the course, applications of the above concepts are discussed. These applications include: wireless multiple access communications, frequency hopping radar and sonar, and cryptography. At the end of the course, students will have enough knowledge of number theory to find applications in their own field of interest and to understand the role of number theory in modern communication systems. In addition, they will understand aspects of wireless systems design.
