Dispersion compensation through digital filtering in an optical OOK modulation system

IEEE Biennial Congress of Argentina, 2018
In this work an optimal linear filter in the sense that minimizes the mean square error between its output and a desired signal is presented. The objective is to mitigate the chromatic dispersion of an optical communications system with an intensity ...

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 ...

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 ...
