Заголовок статьи: Using convolutional encoded preambles for frame synchronizations


The using of preambles for frame synchronization are considered. It is shown that the preamble encoded by a convolutional encoder, in some cases, can reduce the probability of false synchronization compared to a preamble without error correction coding. A technique for detecting of channel inversion and incorrect symbol identification of a pair of elements in the input stream of encoded data that does not require trial decoding is provided.
