Digital Communications 1: Modulation and Coding Course

The two fundamental building blocks of a digital communication system are modulation and channel coding. They enable reliable communication by providing signaling schemes and receiver structures that utilize the available spectrum and power efficiently. Main topics that will be covered in this graduate level class include: A framework for digital communication systems, various M-ary modulation and detection techniques along with their performances, basic principles of channel capacity and coding, linear block codes, convolutional codes and Viterbi decoding algorithm, trellis coded modulation. Students are expected to be familiar with basic concepts of probability | Digital Communications I Modulation and Coding Course B------ ------- -------B Period 3 - 2007 Catharina Logothetis Lecture 13 Last time we talked about The properties of Convolutional codes. We introduced interleaving as a means to combat bursty errors which makes the channel looks like uncorrelated. We also studied Concatenated codes which are simply consist of inner and outer codes. They can provide the required performance at a lower complexity. Lecture 13 2 Today we are going to talk about Shannon limit Comparison of different modulation schemes Trade-off between modulation and coding Lecture 13
