专利内容由知识产权出版社提供专利名称：LDPC decoder, corresponding method,system and computer program发明人：Emmanuel Boutillon,Jacky Tousch,FredericGuilloud申请号：US10742643申请日：20031219公开号：US07174495B2公开日：20070206专利附图：摘要：A decoder of LDPC codewords using the iterative belief propagation algorithmstores a posteriori information on variables. An updating device updates the a posteriori

information on variables, and a first computation device computes variables to constrainmessages from a posteriori information on variables and variable to constraint messagesfrom previous iteration. A second computation device computes a constraint to variablemessages from variable to constraint messages computed by the first computationdevice. A further computation device updates the a posteriori information on variables. Ashuffle device transfers the a posteriori information on variables to the first computationdevice, and a further shuffle device transfers information from the second computationdevice to the storing device. The decoder further includes a device for compression-storage-decompression of the constraint to variable messages. The disclosure alsorelates to a corresponding method, computer program and system.申请人：Emmanuel Boutillon,Jacky Tousch,Frederic Guilloud地址：2 rue de Prague 56100 Lorient FR,17 rue Kerandiou 29217 Le Conquet FR,59 rueBarrault 75013 Parris FR国籍：FR,FR,FR代理机构：Westman, Champlin & Kelly
