Another class of linear codes, known as Convolutional codes. -We studied the structure of the encoder and different ways for representing it. | Modulation Demodulation and Coding Course ------- --- -- --- ------- Period 3 - 2007 Catharina Logothetis Lecture 11 Last time we talked about Another class of linear codes known as Convolutional codes. We studied the structure of the encoder and different ways for representing it. Lecture 11 2 Today we are going to talk about What are the state diagram and trellis representation of the code How the decoding is performed for Convolutional codes What is a Maximum likelihood decoder What are the soft decisions and hard decisions How does the Viterbi algorithm work Lecture 11
