Abstract

One of the most important parts of a telecommunications system is the synchronization establishment between the transmitter and receiver. So in situations where the SYNCHRONIZATION PATTERNs are unknown to the receiver, it is necessary to find the frame structure and bit patterns, Otherwise is impossible transform the bit stream into clear text, or into reliable, cryptographic text, for further processing. Frame structures of different protocols at the physical layer have a fixed or variable lengths and each of these frames have one or more repetitive bit-patterns, depending on the application.. In this paper, a new algorithm for blind detection of bit-patterns in the different frame structures and the BSC channel noise is presented. In this algorithm the first based on the concept of entropy, length of SYNCHRONIZATION PATTERN is found, following by FEATURE EXTRACTION on SLIDING WINDOWs, exact position of the synch pattern is found. It is shown that the proposed algorithm is highly efficient to detect one or more bit-patterns with the large or small length, in the long or short frames with fixed or variable frame structure, while the very low volume of available data and the noisy bit stream.
