Abstract: An apparatus and method for cyclic redundancy check device is provided. The apparatus includes a multiplicity of sub-block CRC parts configured to receive a bit sequence from each sub-block of a transport block that is divided into a multiplicity of sub-blocks and to perform CRC, and a Galois field adding part configured to add second codes, which are output from the multiplicity of sub-block CRC parts, in a Galois field, wherein each sub-block CRC part includes a Galois field multiplying part configured to generate a weight bit sequence by multiplying a first code, which is obtained from CRC calculation of a sub-block weight code that represents a weight allocated to each sub-block, and the bit sequence in the Galois field, and a linear feedback shift register including n-numbered registers and configured to output the second code by adding the weight bit sequence to each register in the Galois field.
