초록

In order to analyze received data in a non-cooperative communication environment, blind estimation of interleaving parameter is required. The previous estimation algorithms estimated interleaving period by exploiting the linear property between the message bits and parity bits of error correction code in noisy channel. In this paper, we improve the performance of interleaving period estimation in fading channel comparing the rank distribution between square matrix composed of received data and that of random data by using probability mass function. The estimation performance is measured by detection probability and false alarm probability and compared with that of the previous algorithms in Rayleigh fading channel through computer simulations.
