Blind Classification of Line-Coding Schemes Based on Characteristic Features

초록

In modern defense technology, signal intelligence plays an important role in military operations as an intelligence source. Among its target signals, telemetry and telecommand signals can use line-coding schemes for their advantageous properties in the presentation of binary data of transmission systems. Therefore, in a non-cooperative context, blind classification of the line-coding scheme is the final crucial step in recovering target information from an unknown received signal. In this paper, we examine the characteristic features of line-coding schemes and then propose a simple blind classification algorithm for the schemes. We also analyze correct classification probabilities of the proposed algorithm in a noiseless and noisy environment through computer simulations. The proposed method can discern line-coding schemes, allowing reconstruction of the original information data.
