Title Proper : ACCELERATING THE CONVERGENCE OF MESSAGE PASSING ON LOOPY GRAPHS USING EIGENMESSAGES
Note : This document is digital این مدرک بصورت الکترونیکی می باشد
Abstract : The field of error correcting codes was revolutionized by the introduction of the Turbocodes and low density parity check (LDPC) codes in the 1990's. These codes demonstrateddramatic performace improvements over any previously known codes, but with a certainamount of latency attached to their decoding algorithms due to the inevitable presence ofloops in the graphs associated with these codes.In this thesis we present the "eigenmessage algorithm" for accelerating the convergenceof message-passing algorithms used for decoding LDPC codes. In the eigenmessage step,elements of a message along an edge of cycle are expressed as a linear combination of thatmessage itself, giving rise to an eigenequation, whose solution- the eigenmessage - is....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
