APPARATUS AND METHOD FOR DECODING LOW DENSITY PARITY CHECK CODE USING PROTOTYPE MATRIX

摘要

Provided is an apparatus and method for decoding a low density parity check (LDPC) code using a prototype matrix. The apparatus includes: a bit input unit for receiving a log likelihood ratio (LLR) value for an input bit; a check matrix processing unit for sequentially processing a parity check matrix for the received LLR value using a prototype parity check matrix through partial-parallel processing; and a bit processing unit for restoring the input bit by determining a bit level from the partial-parallel processed parity check matrix value.
