Patent Searching and Data


Title:
送信装置及び送信方法、受信装置及び受信方法、並びに、プログラム
Document Type and Number:
Japanese Patent JP7077276
Kind Code:
B2
Abstract:
This technique relates to a transmitting apparatus and a transmission method, a receiving apparatus and a reception method, and programs that each enable securing of excellent communication quality in information transmission using an LDPC code.LDPC coding is executed using a check matrix of an LDPC code whose code length is 736 bits and whose code rate is 1/4, and modulation is executed using a repetition unit that has an LDPC code obtained by the LDPC coding, repeatedly arranged therein. The LDPC code includes information bits and parity bits, the check matrix includes an information matrix portion corresponding to the information bits and a parity matrix portion corresponding to the parity bits, the parity matrix portion has a stepwise structure, the information matrix portion is indicated by a check matrix initial value table, and the check matrix initial value table is a predetermined table indicating positions of elements of "1" of the information matrix portion for each eight columns. This technique is applicable to, for example, information transmission using the LDPC code.
