摘要：
The apparatus for appending CRC to the data or signaling to be transmitted in the communication systems is proposed in present invention. If the length of the CRC-bit sequence is 16, one of the CRC generation polynomials listed in present invention can be adopted. If the length of the CRC bit sequence is 18, one of the CRC generation polynomials listed in present invention can be adopted. If the length of the CRC bit sequence is 20, one of the CRC generation polynomials listed in present invention can be adopted. With the optimized CRC generation polynomials proposed in present invention, mistakes in signaling detection can be effectively reduced so that system spectrum utility can be improved.
