Analog Laser Predistortion for Multiservice Radio-Over-Fiber Systems
نویسندگان
چکیده
We have developed some low-cost predistortion circuits to compensate secondand third-order laser distortions in multiservice radio-over-fiber industrial systems. Depending on the predistorter configuration implemented, average reductions of 10–15 dB and of 8–10 dB have been observed in the laser secondand third-order distortions, respectively, within the cellular bands relevant to the European TETRA, GSM, and DCS standards. In particular, the development of the prototypes here illustrated is based on a new and original procedure that formalizes and suitably integrates in a sinergistic way modeling, design, and experimental activities.

Linearization Technologies for Broadband Radio-Over-Fiber Transmission Systems
Linearization technologies that can be used for linearizing RoF transmission are reviewed. Three main linearization methods, i.e. electrical analog linearization, optical linearization, and electrical digital linearization are presented and compared. Analog linearization can be achieved using analog predistortion circuits, and can be used for suppression of odd order nonlinear distortion compon...
متن کاملAdaptive Digital Predistortion of Laser Diode Nonlinearity for Wireless Applications
Nonlinearity of a directly modulated laser diode imposes limitations in the performance of fiber based wireless access schemes. Previously, laser diode nonlinearity has been investigated in CATV related applications. In the CATV scenario, analog optoelectronic compensation schemes have been widely attempted due to the analog nature modulating signals. However, fiber based wireless schemes provi...

متن کاملHigher Order Adaptive Filter Based Predistortion for Nonlinear Distortion Compensation of Radio over Fiber Links
The biggest limitation of Radio over Fiber (ROF) links in a wireless network is its limited dynamic range due to ‘Non Linear Distortions’ (NLD). In this paper a higher order adaptive filter based modeling and predistortion scheme is proposed to compensate this NLD. The filter is adapted from the distortions of vectormodulated symbols, so that no in-depth knowledge of physical link parameters ...
متن کاملA Full-Duplex, Dual-Polarization 10Gbps Radio over Fiber system with wavelength reuse for upstream signal
This study presents a full-duplex Radio-over-Fiber (RoF) system providing the users' wireless access with a bit rate of 10 Gbps over 40 GHz radio carrier. This system can be used in a centralized radio access network (C-RAN) architecture because we provide a fully analog front haul link between central station and base station. We can consider it as infrastructure between remote radio heads (RR...
