Electronics Nuclear engineering The demand for broadband services has driven a number of applications such as, mobile and satellite communications, wireless local area networks (WLANs), wireless local loop and mobile broadband service, etc. However, for wireless communication links, gigabit per second data transmission is required to keep up with the remarkable speed up and huge bandwidth criteria. One of the solutions to overcome this requirement is by using Orthogonal Frequency Division Multiplexing (OFDM) technique to distribute the data over a large number of carriers that are spaced apart at precise frequencies with overlapping bands. Hence by incorporating OFDM along with the optical fiber, the ROF system can be used for both short distance as well as long-haul transmission at very high data rate. In such ROF systems using, broadband microwave data signals are modulated onto an optical carrier at a central station, and then transported to remote sites or base station using optical fiber. The use of FFT for OFDM modulation provides orthogonality to the subcarriers, which prevents the demodulators from seeing frequencies other than their own. Radio over fiber (ROF) is a hybrid system that having both a fiber optic link and free-space radio path that applies the concept when radio signals are transmitted over optical fiber from central station (CS) to several remote base stations (BS). Radio over Fiber (ROF) is consider as integration of optical fiber for radio signal transmission within network infrastructures that is considered to be cost-effective, practical and relatively flexible system configuration for long-haul transport of millimetric frequency band wireless signals. This improves the system flexibility and provides a very large coverage area without increasing t he cost and complexity of the system very much. The project is about to simulate OFDM Radio Over Fiber using Optisystem and Matlab. This particular system was utilized to cam data rates lOGbps and the modulation type for OFDM is 16QAM 4 bit per symbol enough for the study purpose. The finding of this project is the OFDM-ROF is suite with 4G application along with increasing users every year whole the world.
