EVALUATION OF FREQUENCY-PHASE DISTORTIONS IN OPTICAL TELECOMMUNICATIONS USING OFDM

The article proposes a method for monitoring the peak-to-average power ratio (PAPR), and also discusses the results of assessing the sensitivity of optical-OFDM systems to phase-frequency distortions. The results of a study of the noise immunity of an optical-OFDM system for frequency shift relative to the spacing of optical subcarriers are presented.

Water noise immunity improvement in the capacitive sensor panels.

This paper proposes sensing electrode condensed water resistance improvement for the capacitive sensors. It was suggested to use active shield method for the self-capacitance sensors, special sensor construction with using the guard sensor and additional sensor signal processing algorithms.
