Abstract

In this paper, an information recovery process using a horizontal and vertical synchronization frequency detection algorithm, a multiple frame average technique, as well as an image skew correction process is presented. The validity and effectiveness of the proposed procedure are demonstrated using liquid crystal display monitors and a log-periodic dipole array antenna with software-defined radio equipment. In addition, it is shown that real-time video information recovery is possible from a distance of 10 m behind a concrete wall.
