Experimental investigation of underwater turbulence effect on BER for orthogonal OOK modulation
IEEE International Conference on Electro/Information Technology, 2014Underwater laser communication is a very attractive and efficient way to communicate in oceanic environment without disturbing the marine life. Though acoustic communication is very popular in this kind of communication system, the laser communication would be the best way for transmitting and receiving signal or data in deep oceanic environment due to

Performance analysis of OOK modulation scheme with spatial diversity in atmospheric turbulence
2014 23rd Wireless and Optical Communication Conference (WOCC), 2014Free space optical (FSO) communication is a cost effective and high bandwidth access technique. A major impairment in FSO links is turbulence induced fading which severely degrade the link performance. Spatial diversity is one of the mitigation techniques for atmospheric turbulence to improve the bit error rate performance.

Ultrasonic wireless communication in air using OFDM-OOK modulation
2014 IEEE International Ultrasonics Symposium, 2014A short-range multi-channel airborne ultrasonic data communication system using orthogonal frequency division multiplexing (OFDM) is described in this paper. An on-off keying (OOK) based OFDM modulation scheme was implemented successfully in the system by using a pair of commercially available air-coupled capacitive ultrasonic transducers.

Dual Modulation of QPSK and OOK Using Silicon Microring Modulator
2021In this paper, we experimentally demonstrate an integrable and wavelength preserving dual-modulation format for the simultaneous generation of quadrature phase-shift keying(QPSK) signal over the on–off keying (OOK) signal. We have demonstrated the successful operation of dual modulation by using three microring modulators in two different ...

LED Modelling for Efficient LiFi Modulator Design to Accelerate OOK
IECON 2022 – 48th Annual Conference of the IEEE Industrial Electronics Society, 2022This paper studies the response of a Light Emitting Diode (LED) to a stepwise change of the power delivered by a current or voltage supply. This study contributes to the design of efficient electronic circuits to generate On-Off Keying modulation for optical wireless communication using LEDs as an emitter.
