Channel coding:Transforming signals to improve communications performance by increasing the robustness against channel impairments (noise, interference, fading, ) | Digital Communications I Modulation and Coding Course B------- ------- ------B Period 3 - 2007 Catharina Logothetis Lecture 9 Last time we talked about Evaluating the average probability of symbol error for different bandpass modulation schemes Comparing different modulation schemes based on their error performances. Lecture 9 2 Today we are going to talk about Channel coding Linear block codes The error detection and correction capability Encoding and decoding Hamming codes Cyclic codes Lecture 9
