High-order transverse-magnetic mode Mach-Zehnder modulator for OOK modulation

2018 Asia Communications and Photonics Conference (ACP), 2018
We present a silicon Mach-Zehnder modulator (MZM) for high-order TM modes. A single-drive push-pull electrode with L-shaped vertical PN-junctions is employed to provide a high modulation efficiency.

Cooperative VLC system using OOK modulation with imperfect CSI

Physica Scripta, 2023
Abstract Visible light communication (VLC) is one of the aspirant tools for high data rate communication. VLC system employed in a large room requires cooperative transmission for reliable end-to-end communication. Cooperative communication (CC) utilizes several relay approaches to forward the message from transmitter to envisioned ...

Experimental investigation of underwater turbulence effect on BER for orthogonal OOK modulation

IEEE International Conference on Electro/Information Technology, 2014
Underwater 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

An inductive wireless telemetry circuit with OOK modulation for implantable cardiac pacemakers

2015 IEEE 11th International Conference on ASIC (ASICON), 2015
An 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), 2014
Free 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.

Generalized Blind Detection of OOK Modulation for Free-Space Optical Communication

IEEE Communications Letters, 2017
For 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.

20-Gbps 60-GHz OOK modulator in SiGe BiCMOS technology

2012 International Symposium on Signals, Systems, and Electronics (ISSSE), 2012
This 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.

Study on transmission performance of optical OOK and PSK modulation formats

2017 16th International Conference on Optical Communications and Networks (ICOCN), 2017
By solving Schrodinger equation in standard Split-Step Fourier Transform (SSFT) method, the NRZ, 33%RZ, 50%RZ, CSRZ, DPSK, 33%RZ-DPSK, 50%RZ-DPSK and CSRZ-DPSK were simulated in 40G bit/s single channel transmission system with the influence of dispersion, nonlinearity and polarization mode dispersion.

Applying OOK modulation to reduce the inter-carrier interference in OFDM

2007 IFIP International Conference on Wireless and Optical Communications Networks, 2007
Orthogonal 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 ...
