Kolmogorov-Smirnov 검정을 이용한 인터리버 파라미터 블라인드 추정

초록

In this paper, we propose a blind estimation algorithm for interleaver period by utilizing received data especially when the transmitter in a communication system includes a convolutional encoder and a block interleaver. We first investigate the rank of the matrices composed of block interleaved convolutional codewords. And then, we compare rank deficiency distribution of matrix composed of received data with that of matrix composed of randomly generated binary data by using Kolmogorov-Smirnov Test (KST) to estimate the interleaver period. The estimation performance in the binary symmetric channel(BSC) is analyzed through computer simulations and compared with that of the previous estimation algorithm in terms of detection probability.
