Generalized Blind Detection of OOK Modulation for Free-Space Optical Communication
IEEE Communications Letters, 2017For optimal detection of ON – OFF keying symbols in free-space optical (FSO) communication, the receiver requires the instantaneous channel fading coefficient. In this letter, to increase the bandwidth efficiency of the FSO channel, we propose a blind data detection method, i.e., without requiring transmission of any training symbols.

An inductive wireless telemetry circuit with OOK modulation for implantable cardiac pacemakers
2015 IEEE 11th International Conference on ASIC (ASICON), 2015An inductive wireless telemetry circuit for implantable cardiac pacemakers is presented in this paper. An internal coil in the titanium case transmits the detected cardiac data into the coil of the outside programmer. The configuration data and the commands from the programmer are sent to the pacemaker through the same pair of coils to save volume of ...

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.

20-Gbps 60-GHz OOK modulator in SiGe BiCMOS technology
2012 International Symposium on Signals, Systems, and Electronics (ISSSE), 2012This paper presents design and characterization of a 60-GHz On-Off Keying (OOK) modulator for low-power ultra-high-speed wireless communications. The circuit operation relies on the active control of the load impedance of a differential pair; in addition, a matched always-off differential pair increases the isolation by cancellation of the off currents.

Applying OOK modulation to reduce the inter-carrier interference in OFDM
2007 IFIP International Conference on Wireless and Optical Communications Networks, 2007Orthogonal frequency division multiplexing (OFDM) has become one of the promising technologies for the next-generation communications systems to support high-speed high-quality digital transmission and reception. However, the frequency misalignment between transmitter and receiver results in the inter-carrier interference (ICI), which degrades the ...

A 1.9 GHz CMOS High Isolation Absorptive OOK Modulator
IEEE Microwave and Wireless Components Letters, 2015This 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, 2008Chaotic 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.
