APPARATUS AND METHOD FOR GENERATING PARITY CHECK MATRIX FOR LDPC CODE AND LDPC ENCODING/DECODING APPARTUS USING THE SAME

摘要

Provides are an apparatus and method for generating a LDPC code having a simple coding structure, a fast decoding convergence speed, a variable information length, and a variable coding rate, and a LDPC encoding/decoding apparatus using the same. The apparatus for generating a LDPC code includes a first parity check matrix generating unit for generating a first parity check matrix formed of a first information block and a parity block; and a q parity check matrix generating unit for generating a q parity check matrix by adding a q information block to the generate q-1 parity check matrix where 1q≤Q and Q is an integer greater than 2.
