“…A reducedcomplexity algorithm introduced in [22] may be used to evaluate these quantities. Moreover, (16) and (18) are only employed in the SYNCH state in presence of errors and in the HUNT state. When the channel is relatively clear, (16) and (18) are then not too frequently evaluated, and the complexity remains of the same order of magnitude as that of the techniques presented in [5] or in [6], [13], [14].…”

“…This increases the throughput, but, any error upon reception of the burst header may result in the loss of the complete burst. Simultaneous synchronization for several frames are thus considered in [16] to improve FS efficiency. Using a hold-and-sync(hronize) approach, where a whole burst is processed at each step, may significantly improve the performance of the FS.…”

In many communication standards, several variable length frames generated by some source coder may be aggregated at a given layer of the protocol stack in the same burst to be transmitted. This decreases the signalization overhead and increases the throughput. However, after a transmission over a noisy channel, Frame Synchronization (FS), i.e., recovery of the aggregated frames, may become difficult due to errors affecting the bursts. This paper proposes several robust FS methods making use of the redundancy present in the protocol stack combined with channel soft information. A trellis-based FS algorithm is proposed first.Its efficiency is obtained at the cost of a large delay, since the whole burst must be available before beginning the processing, which might not be possible in some applications. Thus, a low-delay and reduced-complexity Sliding Window-based variant is introduced. Second, an improved version of an on-the-fly three-state automaton for FS is proposed. Bayesian hypothesis testing is performed to retrieve the correct FS. These methods are compared in the context of the WiMAX MAC layer when bursts are transmitted over Rayleigh fading channels.

“…The reliability for backside data disposal and the whole performance of a communications system are insured by the technique of frame synchronization by checking the frame synchronization mark and picking up the frame data [1,2], [3]. The technique of frame synchronization has gained considerable attention in theory and application, such as the selecting standard for synchronization header model [4,5], the searching arithmetic for synchronous header [6,7], design of appointed frame synchronization system [8][9][10], and so on.…”

In order to improve the frame synchronization performance of the adaptive length frame transmission system, a frame synchronization scheme is proposed. The scheme considers the false loss probability relating to the bit error rate and the false alarm probability relating to the model of synchronous header are considered synthetically. Then the performance formulas of general frame synchronization are given and analyzed to obtain the relevant frame synchronization parameters. In the end, based on the frame synchronization parameters, the scheme performance of adaptive length frame synchronization is simulated. The simulations show the adaptive length frame transmission system can realize frame synchronization effectively.

Aiming at the difficult for identifying the alterable length frames, a specific method of frame synchronization is proposed to solve the problem of frame synchronization for the adaptive frame length system. In the novel method, the core innovation about new frame format has been done. Based on the new frame format, the alterable length frames are demarcated by searching Frame Synchronization Header bit by bit and checking Frame Synchronization Header frame by frame. Then the relevant performance parameters are analyzed and educed. Finally, a simulation system is designed to verify the proposed method. By simulating, the reference values for the rear protect time and the ahead protect time are given to ensure the probability of frame synchronization method. The significance of solving the problem is to ensure the reliability of data transmission and processing for the adaptive frame length system. Compared with previous work, the novel method can enter the frame synchronization more easily.
