Light emitting diodes (LEDs) are used in Li-Fi as visible light transmitters, therefore, only intensity modulated direct detected modulation techniques can be achieved. It is a significant issue in communication system noise source in WDM systems are amplifier noise & thermal noise in receivers. Li-Fi is the fully networked solution for multiple users that combines communication and illumination simultaneously. The source code of the framework is made available for the use of the research community. It is the process of conveying message signal, a digital bit stream or analog audio signal inside another signal can be physically transmitted. Simulation results are produced to demonstrate the mobility and handover capabilities, and the performance gains from the LiFi-WiFi hybrid system in terms of packet delay, throughput, packet drop ratio (PDR), and fairness between users. We implement fiber optic communication in optisystem by Modulation: BER optimization in fiber optic communication: We divide bit error rate by total number of transferred bit during a studied time interval.Įye diagram analyzer block of optisystem software display multiple trace of modulated signal to produce eye diagram.In digital transmission we alter the number of bit errors due to interference distortion, noise or synchronization error.We provided the simulation models are: Bit error analyzer: OPTISYSTEM PROJECTS FOR STUDENTS Simulation model for ROF system analyzer:
