Ultrasonic wireless communication in air using OFDM-OOK modulation

2014 IEEE International Ultrasonics Symposium, 2014
A 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.

A 1.9 GHz CMOS High Isolation Absorptive OOK Modulator

IEEE Microwave and Wireless Components Letters, 2015
This letter presents a high-isolation absorptive 1.9 GHz on-off keying (OOK) modulator in 90 nm CMOS process. The RF leakage-canceling technique is developed to suppress the RF leakage by combining it with its inverse replica at the output. The transform-typed baluns are used for the input and output matching such that the modulator input and output ...

A Chaotic Duffing Receiving System Based on OOK Digital Modulation

2008 4th International Conference on Wireless Communications, Networking and Mobile Computing, 2008
Chaotic detection is to test weak signals based on trajectory changes of chaotic system. The traditional Duffing system is sensitive to frequency of periodical sine signals, but it is only suitable for detecting low-frequency signals, and can not be used to detect those of high-frequency.
