Title:
移動通信システムで不均一誤り確率を有する符号化によるデータ送受信方法及び装置
Document Type and Number:
Japanese Patent JP2007515122
Kind Code:
A
Abstract:
Disclosed is an apparatus for transmitting information bits after coding the information bits with Low Density Parity Check (LDPC) codes having unequal error probability values in a wireless communication system which channel-codes and transmits the information bits. The apparatus includes a LDPC encoder for mapping high information bits to low variable nodes and low information bits to high variable nodes, the high information bits having high importance priorities and the low information bits having low importance priorities from among the information bits, wherein the low variable nodes are variable nodes having low error probability values and the high variable nodes are variable nodes having high error probability values in a factor graph of the LDPC codes.
