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...
متن کاملPerformance Research of Modulation for Optical Wireless Communication System
There are many modulation methods suitable for optical wireless communication. OOK, PPM are adopted widely in optical wireless communication for its high average-power-efficiency. DPPM, DPIM and DH-PIM are three new modulation methods for optical wireless communication, which may be the substitutes of PPM because of their better performance in power efficiency and bandwidth efficiency. In this ...
متن کاملPerformance Analysis of High Speed Optical Communication using FBG
This paper based on study of communication system over fiber optics. To design high speed system with high performance it is necessary to compensate the dispersion with the help of Fiber Bragg Grating. The performance of communication system simulation is done on Optisystem simulator Vr.12 at different parameters of the system. A high speed NRZ signal is transmitted over SSMF. By simulating the...
متن کاملAn 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...
متن کاملPerformance of a Precoded High Speed Wireless Communication System over Time-varying Indoor Channels
A detailed and realistic time-varying channel model is used in the simulation of a 20-Mbps indoor wireless communication system that uses a DFE on the reverse link and a Tomlinson-Harashima precoder on the forward link to mitigate ISI. The motivation of such an asymmetric scheme is to minimize the hardware complexity of the portable unit. Results confirm the viability of this system by quantify...
