Interleaving is a widely used technique to overcome the burst error in systems featuring error correction. In a non-cooperative environment such as satellite signal in which receiver is not aware of the structure of transmitter, interleaver should be identified, otherwise it would be impossible to identify the residual components and completing the hearing process. In satellite systems, it is a common practice to use a combinatory coding block, including reed-solomon codes and an interleaver with convolutional codes. This research presumes that convolutional code is identified and an algorithm is suggested for recognition of interleaver. In this algorithm, based on the presence of reed-solomon code, interleaving period is identified, non-binary field degree is calculated, and a factor meeting the length of reed-solomon code would be the interleaver depth. Comparing with other available methods, in our suggested algorithm, computational complexity are reduced to and simultaneity and accuracy of identification is higher. Additionally, Based on the simulations performed, the in order to identify the depth of Interleaver and have been used in order to synchronization.
