Student:  Jalal Etesami Advisor: Prof. Dr.-Ing. Werner Henkel Time frame: Fall 2008         Description: We introduce a new algorithm for constructing LDPC codes based on a Protograph. With Protographs, we have a base graph (mother graph), which is duplicated a number of times followed by a special edge permutation obtaining the largest

Student:  Behrouz Touri Advisor: Prof. Dr.-Ing. Werner Henkel Time frame: Spring 2008         Description: Binary linear codes are one of the main tools for error-control coding over telecommunication channels and data storage devices. However, despite of having very simple encoder structures, their optimum decoding is usually a hard problem in practice. In
