“…The blind estimation of convolutional interleaver was studied in [7,8]. In [7], the intercepted data is arranged into an interception matrix. Then, according to the rank of interception matrix, some parameters of the convolutional interleaver are estimated by comparing the positions of codewords between different interleave periods.…”

Interleaving plays an important role in many wireless communication systems, which is used to cope with burst errors and improve the reliability of data transmission. In this paper, we propose a new method to blindly estimate the parameters of convolutional interleaver in a non-cooperative context. The proposed method exploits both the property of interleaved stream and the deinterleaving technique. The product of the depth and width of the interleaver is firstly determined by analyzing interleaved data stream. Then the interleaved data stream is let to pass through a series of reconstructed deinterleavers. Thus the delay, the depth and width of the convolutional interleaver can be estimated by analyzing the deinterleaved data streams. Compared with other algorithms, the proposed method significantly reduces the searching scope and improves computational efficiency. Simulation results show that the algorithm has good performance even if errors exist.

“…For instance when the code is a convolutional code, this allows to spread the burst errors in remote locations and convolutional decoding performs much better. This problem has been already addressed in a series of papers [46][47][48][49][50]. All these papers assume that the interleaver is structured (a convolutional interleaver [46][47][48][49] or an helical scan interleaver [50]).…”

All these papers assume that the interleaver is structured (a convolutional interleaver [46][47][48][49] or an helical scan interleaver [50]). It should be said here that the methods used in these papers make heavily use of the particular structure of the interleaved that is considered and some of these methods are highly sensitive to noise [47,49] or do not apply when there is noise [46,48].…”
