A Scheme to Improve SNR of Received EMI Signal from Information Display Device

This paper analyzes the characteristics of the display signal for an information display device and proposes a synchronization algorithm using its periodicity. The synchronization is the most important to enhance the signal-to-noise ratio (SNR), and it requires two kinds of phase information. One is the phase of the frame, and the other is the phase of the carrier frequency. Hence, this paper describes a methodology to estimate the phase terms, and the result conducted measurement data is verified.
