Abstract : We consider the transmission of successive short packets. Each of them combines information to be transmitted (codeword) with information for synchronizing the frame (SW). For short packets, the cost of including SW is no longer negligible and its design requires careful optimization. In particular, a trade-off arises depending on the way the total transmit power is split among the SW and the codeword, or on the way the total frame length is split among the SW length and the codeword length. Assuming optimal finite-length codes, we develop tight upper bounds on the probability of erroneous synchronization, for both frames with concatenated SW and frames with superimposed SW. We use these bounds to optimize this trade-off. Simulation results show that the proposed bounds and analysis have practical relevance for short-packet communication system design.
