In this paper, a transform domain processing (TDP) based channel estimation method for orthogonal frequency-division multiplexing (OFDM) Radio-over-Fiber (RoF) systems is proposed. Theoretically investigation shows that TDP can greatly reduce the number of required training symbols. An 8 x 4.65 Gb/s multi-user OFDM RoF system over 40 km fiber link and 60 GHz wireless link is experimentally demo...

Wireless coverage of the end-user domain; be it outdoors or indoors, is poised to become an essential part of broadband communication networks. In order to offer integrated broadband services (combining voice, data, video, multimedia services, and new value added services), systems will need to offer higher data transmission capacities. The need for increased capacity per unit area leads to hig...

1. Introduction Radio on Fiber (RoF) system can provide low-cost and high-performance radio-wave distribution by using remote access units (RAUs) where lightwave modulated by radio-wave is converted to radio-wave by a high-speed photodetector (PD) [1]. In microwave bands, RoF systems are successfully used for mobile services to provide signals to the mobile terminals located at such shadowing a...

In this study the impact of a Radio-over-Fiber (RoF) subsystem on the performance of Orthogonal Frequency Division Multiplexing (OFDM) system is evaluated. The study investigates the use of Multi-Layered Perceptron (MLP) and Radial Basis Function (RBF) neural networks to compensate for the optical subsystem nonlinearities in terms of bit error rate, error vector magnitude, and computational com...

The paper analyzes three handoff algorithms which are used in Radio-over-Fiber (RoF) networks at 60 GHz. Specifically, the Virtual Cellular Zone (VCZ) and the Moving Extended Cell (MEC), are presented, against the Traditional Handoff (THO) algorithm, which is the simplest proposed solution in such networks. The mathematical analysis regarding packet losses for all three handoff algorithms is pr...
