Patent Searching and Data


Title:
構造的低密度パリティ検査符号を用いる通信システムにおけるデータ送信/データ受信のための装置及び方法
Document Type and Number:
Japanese Patent JP4361924
Kind Code:
B2
Abstract:
Provided is an apparatus and method for transmitting/receiving data in a multi-antenna communication system using a structured Low Density Parity Check (LDPC) code. The transmitter performs structured LDPC coding on input information data using a structured LDPC code, parallel-converts a structured LDPC codeword generated by performing the structured LDPC coding, in units of groups having a predetermined size, and transmits data. The receiver receives a plurality of parallel data streams, serial-converts the received parallel data streams in units of groups having a predetermined size, and performs structured LDPC decoding on the data which was serial-converted group by group, using a structured LDPC code.
