Question: In 5G NR (New Radio), what is the primary purpose of cyclic generator polynomials in the CRC calculation process for input bits?
Option 1: To systematically encode the input bits, ensuring the remainder is 0 when divided by the CRC generator polynomial, thus enabling error detection.
Option 2: To scramble the input bits for security enhancement in the transmission process.
Option 3: To prioritize the transmission of parity bits over the original input sequence.
Option 4: To determine the optimal CRC length based on the input sequence size.
Explanation: The cyclic generator polynomials play a crucial role in the CRC calculation process. By dividing the polynomial representation of the input bits and parity bits by the CRC generator polynomial, a remainder of 0 is achieved, which is vital for effective error detection in wireless communications. This ensures any transmission errors can be identified at the receiver end via the CRC check.
