This paper consist a simulation study of nonlinear distortion (NLD) for radio over fiber (RoF) link. The simulation is performing on OptiSystem platform. The investigation of the nonlinear effect in done by electrical cancellation point, output power, oscilloscope visualizer, types of modulation and laser power etc.

The demand of mobile communications in the modern world is increasing day by day and subscribers for the mobile communication technologies are growing rapidly. The data transfer rate should be maximum for uninterruptable communication .Therefore, the Radio over fiber system along with wireless communication, is used for the high speed data transfer. This combination will increase the capacity f...

An integrated optical millimetre-wave signal generator based on a coupled microring resonator, which doubles the frequency of the electrical signal driving a phase modulator, is proposed and experimentally demonstrated for future radio-over-fibre systems. The coupled microring notch filter was fabricated on a silicon-on-insulator wafer. A high extinction ratio optical millimetre-wave signal was...

Future communication needs to be ubiquitous, broadband, convergent, and seamless. Radio over fiber (RoF) technology is one of the most important enabler in access network for the technologies. Adoption of RoF faces bottleneck in optoelectronics, that they are still expensive, high power consumption, and limited in bandwidth. To solve the problem, transceiver in remote antenna unit (RAU) is deve...

The main aim of this paper is to analyze the influence of the modulation techniques; on the performance of coded orthogonal frequency-division multiplexing (COFDM) based Radio over Fiber (RoF) system. The modelling of the COFDM scheme for RoF system has been completely done by using software Optisystem. Both analysis and simulation results are presented for 16-QAM and 16-QPSK modulation techniq...
