Radio-over-Fiber (RoF) emerges as a promising solution to achieve cost-effective radio-antennas backhauling. The limited dynamic range of analog optical transmission is known as one of the most penalizing limitations of analog RoF links. Thus, without a special care to RoF signal impairments, the wireless system capacity may be seriously degraded. In this paper, we propose an impairment-aware RoF-based cellular backhauling system called GeRoFAN aiming to preserve the capacity of the radio system while using efficiently the optical capacity. Supported by an analytical modeling of RoF physical impairments, we develop an evolutionary multi-objective heuristic called PaGeO (Pareto-based Genetic Optimization) exploiting the concept of Pareto optimization to determine the best backhauling strategy for the GeRoFAN control plane. We outline through numerical results that our impairment-aware backhauling solution computed by PaGeO, applied to LTE radio cellular system, outperforms alternative backhauling policies. We also highlight the impact of RF cellular planning on the tradeoff optimization achieved by PaGeO.

“…However, RoF systems are vulnerable to non-linearities in the optical subsystem that cause degradation of the system performance. The main areas of research in RoF include microwave and millimeter-wave RoF [4][5][6], RoF-based wireless local area networks (WLANs) [7,8], RoF-based cellular systems [8], subcarrier multiplexed RoF systems [8], RoF-based wavelength division multiplexing (WDM) [9] and RoF-based photonic CDMA [10]. In particular, estimation methods, modelling the radio subsystem, modelling the optical subsystem and multiple access techniques are regarded as the most important investigation topics in this context.…”

AbstractÑIn this paper the impact of a Radio over Fibre (RoF) subsystem on the capacity performance of Wideband Code Division Multiple Access (WCDMA) is evaluated. The study investigates the use of pilot aided channel estimation to compensate for the optical subsystem nonlinearities for different channel conditions, estimation intervals, and coding schemes. The results show that pilot aided channel estimation is an effective method for compensating the composite impairments of the optical subsystem and the RF channel. It is found that there is always a suitable pilot power level which maximises the system capacity performance regardless of coding scheme and channel condition. Also, the peak capacity is only slightly affected by a decrease in the estimation interval.

With the advancement in the technology, the needs of the users are also growing. The demand for higher bandwidth is one of these requirements. In order to fulfill this, Fiber Optic communication is developed. It transfers the data in the form of light waves and also achieves higher data transmission rate by facilitating the wider bandwidth for transmission. This mode of communication uses various encoding schemes such as NRZ and various communication channels to improve the quality of communication.The implementation is done by using optisystem. The various encoding schemes are implemented with three different communication channels. It is observed that MDRZ outnumber rest of the encoding scheme with respect to the value of BER and Q. Factor.
