In order to get the frame synchronization information on the unknown lines in digital communication,a method of blind detecting sub synchronous sequence is presented.By modeling frame synchronization,the relationship between the probability of detecting the sub synchronous sequence and the length of data is gained in the word frequency statistics with different word widths.According to this relationship,the blind detecting sub synchronous sequence of unknown lines with any bit-start in error conditions is realized by conducting the word frequency statistic and adjusting the word width and data length,which makes it possible to get the whole frame synchronization information on unknown lines.
