Principles of Digital Communication II
This MIT OpenCourseWare course continues the digital communication sequence begun in 6.450, focusing on coding techniques that approach the Shannon limit for AWGN channels. Topics cover binary linear block codes, Reed-Muller, Reed-Solomon, and BCH codes, convolutional codes and the Viterbi algorithm, trellis representations, and codes on graphs including sum-product, min-sum, and BCJR decoding algorithms. Later sessions examine turbo codes, LDPC and RA codes, and iterative decoding performance, followed by bandwidth-limited coding methods such as lattice codes, trellis-coded modulation, multilevel coding, and shaping, with equalization of linear Gaussian channels if time allows. The course includes lecture notes, problem sets, and exams from MIT's Electrical Engineering and Computer Science department, freely available under a Creative Commons license. No enrollment or certificate is offered; materials are self-study resources for advanced students already familiar with the first-term material.
