MIT 6.451 Principles of Digital Communication II - Spring 2005

This course is the second of a two-term sequence with 6.450. The focus is on coding techniques for approaching the Shannon limit of additive white Gaussian noise (AWGN) channels, their performance analysis, and design principles. After a review of 6.450 and the Shannon limit for AWGN channels, the course begins by discussing small signal constellations, performance analysis and coding gain, and hard-decision and soft-decision decoding. It continues with binary linear block codes, Reed-Muller codes, finite fields, Reed-Solomon and BCH codes, binary linear convolutional codes, and the Viterbi algorithm.

More advanced topics include trellis representations of binary linear block codes and trellis-based decoding; codes on graphs; the sum-product and min-sum algorithms; the BCJR algorithm; turbo codes, LDPC codes and RA codes; and performance of LDPC codes with iterative decoding. Finally, the course addresses coding for the bandwidth-limited regime, including lattice codes, trellis-coded modulation, multilevel coding and shaping. If time permits, it covers equalization of linear Gaussian channels.

Comment1 Charles L Carter, December 24, 2009 at 6:11 p.m.:

The course is very informative, I really like it simply because it refresh what I had and it been a while since I took the course. I graduated back in June of this year with a Bachelor EECT (2009). And at my age (55) and retired Military I don’t retain it as well as I used to and I just realize how much I had forgotten. I really like it and I think it is good for Alumni’s to come back too and get a refresher and I don’t mine donating to it. VERY HELPFUL.
