Module 5 introduces the concept of error correcting codes to improve system performance. These solutions are extremely effective, but require additional complexity and some bandwidth efficiency trade-offs. As an example, we introduce convolutional code fundamentals. PartA of module 5 is an introduction and motivation for the use of forward error correction (FEC). We focus on the role of coding and basic parity-based protection. We introduce several metrics for FECs. PartB of Module 5 examines convolutional coding. Detailed descriptions of the convolutional encoder are provided, with varied encoder representations (e.g., finite-state models, trellis diagrams), and decoding principles using the Viterbi algorithm. PartC of Module 5 examines the Viterbi decoder in some detail. We cover convolutional decoding topics (complexity, free distance, coding gain), plus additional tools and examples.
