The objective of this study is to assess comparatively the efficiency of the permutation-based frame synchronization method for the syncword length of 16 and 8 elements. The proposed method employs a permutation of elements encoded using a fixed-length code. In this method, the maximum value of the minimum Hamming distance between the binary representation of permutation and each of its circular shifts is used. The results show that, for a syncword of length 16, the maximum value of the minimum Hamming distance is 30. A computer simulation model for a frame synchronization system is developed. The indicators for synchronization are determined using the parameters calculated for bit error rate values of 0.4 and 0.495, a correct synchronization probability not less than 0.9997, and a false synchronization probability not greater than 3E-4. The results show that a syncword of length 16 increases the number of bits required in comparison with a syncword of length 8. However, a larger syncword length is required to ensure the cryptographic security, especially, for a three-pass permutation-based protocol.
