This repository contains the material used- references, assignments and tutorials- for the January - May 2021 offering of EE6143: Advanced Topics in Communications (5G NR) at IIT Madras for which I served as a Teaching Assistant. Taught by Prof. Radhakrishna Ganti, this course covers the fundamentals of wireless communication and some of the 5G NR specifications. Broadly, the topics covered include-

• OFDM
• 5G NR: time and frequency structure of data
• SSB, MIB and SIB
• TDD
• PRACH
• FEC in 5G NR
• MIMO in 5G NR
• DMRS
• RAN, 5G Core, QoS and slicing

• Assignment1: a programming assignment that introduces students to MATLAB and has them simulate the waterfall curves for an AWGN channel

• Assignment2: a warm up theory assignment on random variables

• Assignment3: a programming assignment that involves the simulation of transmission using OFDM with AWGN and multipath fading channels

• Assignment4: a theory assignment on OFDM in the context of 5G NR

• Assignment5: a theory assignment on SIB, TDD and PRACH in 5G NR

• Assignment6: a programming assignment that involves the simulation of LDPC coded transmission using OFDM for an AWGN channel

• Tutorial: an introduction to MATLAB and some of the functions likely to be used in the assignments issued to the students
