Blind Estimation of Communication Emitter Feature Parameters

In this paper, the problem of blind estimation of the convolutional interleaving parameters, an important feature parameters of communication emitter, is studied. The unitive mathematical model of the convolutional interleaver was presented and the blind estimation of convolutional interleaving parameters has been investigated using characteristics of scrambled sequences in this paper. The proposed algorithm uses only the intercepted interleaved stream and computer simulation results show that the proposed algorithm can provide good performance even when the bit error rate is 0.30.
