摘要： A decoding device for decoding an LDPC (Low Density Parity Check) code. The decoding device may include a first operation unit for performing a check node operation for decoding the LDPC code, the operation including an operation of a nonlinear function and an operation of an inverse function of the nonlinear function; and a second operation unit for performing a variable node operation for decoding the LDPC code. The first operation unit includes a first converting unit for converting a first quantization value assigned to a numerical value into a second quantization value representing a numerical value with a higher precision than the first quantization value, and a second converting unit for converting the second quantization value into the first quantization value.
