A High-Speed and Long-Reach PAM4 Optical Wireless Communication System

Performane Evaluation of High Speed Optical Wireless Communication System

In this paper, performance evaluation of high speed optical wireless communication has been observed. It has been observed that Q value lies in the range of 26 to 15 dB and 25 to 14dB in the transmission power (8dBm) and attenuation (23dB) at distance of 800m to 2000m in free space optical communication. Similarly BER lies in the range of 10 to 10 4 and 10 to 10 in the transmission power and at...

An LDPC-COFDM based High Speed Mobile Wireless Communication System

Coded Orthogonal Frequency Division Multiplexing (COFDM) is very well matched to the terrestrial channel, being able to cope with severe multi-path and the presence of co-channel narrowband interference. This paper presents an image and video transmission scheme based on COFDM for high speed mobile wireless communication system in which a good Rate-Compatible Low-Density Parity-Check codes stru...

High-Speed Power-Efficient Indoor Optical Wireless System

Convergent optical wired and wireless long-reach access network using high spectral-efficient modulation.

To provide broadband services in a single and low cost perform, the convergent optical wired and wireless access network is promising. Here, we propose and demonstrate a convergent optical wired and wireless long-reach access networks based on orthogonal wavelength division multiplexing (WDM). Both the baseband signal and the radio-over-fiber (ROF) signal are multiplexed and de-multiplexed in o...

Machine Learning Equalization Techniques for High Speed PAM4 Fiber Optic Communication Systems

In this work, we apply machine learning regression and classification algorithms to the problem of equalization and detection in high-speed fiber optic communication systems. Introduction Conventional linear feed forward equalizers (FFEs) are widely used in fiber optic communication systems to mitigate inter-symbol interference resulting from a limited bandwidth of electro-optic components, as ...
