Part 3: Channel Coding: From DMCs to Gaussian Channels
Chapter 11: Coding for the Gaussian Channel
Intermediate~210 min
Learning Objectives
- Describe lattice codes and explain how they achieve AWGN capacity
- Compare turbo, LDPC, and polar codes from an information-theoretic perspective
- Explain Ar\i kan's channel polarization phenomenon and how it enables polar codes
- Decompose the gap to capacity into coding gain and shaping gain
- Explain probabilistic shaping and how it closes the shaping gap
- Relate these coding constructions to practical deployments in 5G NR
