ABSTRACT:
A decoding apparatus for low density parity check codes includes a variable-to-check message generator and a check-to-variable message generator. The variable-to-check message generator includes a variable-to-check processing unit block, provided with an adder, and which is arranged between registers corresponding to locations of ‘1’s in a check matrix. The check-to-variable message generator includes a check-to-variable processing unit block, provided with a comparator, between registers corresponding to locations of ‘1’s in the check matrix. The decoding apparatus for low density parity check codes is simple in configuration and is able to perform high speed processing without using RAMs without the necessity of performing complex control operations.
