As for frame synchronizer, the recognizer of the frame pattern and its performance are analyzed in details. The probability of catching frame pattern upon one pass is deduced. Based on these, the relationship between optimum frame pattern length and the frame length , the allowable error tolerance and the channel errors, the protecting parameter α、βand the threshold level are derived. Consequently, a new type of adaptive frame synchronizer is presented.
