Permutation-Based Frame Synchronisation Method for Short Packet Communication Systems

The project was undertaken to design frame synchronization method for short packet communication systems with non-separable factorial coding. The method employs as a syncword a permutation with the maximum value of the minimum Hamming distance from its binary representation to all its cyclic shifts. The proposed method makes it possible to establish frame synchronism under conditions of high-intensity noise in communication channel. This result is achieved due to correlation and majority processing of the received fragments. The method can be applied to reduce synchronization acquisition time and to increase the stability of telecommunication system. An algorithm to apply the proposed method has been developed and implemented.
