“…RoF systems are now being used extensively for enhanced cellular coverage inside buildings such as office blocks, shopping malls and airport terminal. RoF is fundamentally an analog transmission system because it distributes the radio waveform, directly at the radio carrier frequency, from a central unit to a Radio Access Point (RAP) [2].…”

Optical networks are fast, robust and error free, however, there are nonlinear obstacles preventing from being perfect media. The performance of wavelength division multiplexing (WDM) in radio over fiber (RoF) systems is found to be strongly influenced by nonlinearity characteristics inside the fiber. The effect of four wave mixing (FWM) as one of the influential factors in the WDM for RoF. From the results obtained, it is found that the FWM effects have become significant at high optical power levels and have become even more significant when the capacity of the optical transmission line is increased, which has been done by either increasing the channel bit rate, and decreasing the channel spacing, or by the combination of both process. It is found that when the channel spacing is 0.1 nm, 0.2 nm and 0.5 nm the FWM power is respectively, becomes about -59 dBm, -61 dBm and -79 dBm. The simulation results obtained here are in reasonable agreement as compared with other numerical simulation results obtained, elsewhere, using different simulation tools.

“…However, widespread introduction of BSs to wireless local area networks is predicated on reducing the size and the cost. For this purpose, the radio-over-fiber (ROF) technique has attracted a great deal of attention [5], [6]. This technique makes it possible to process complicated operations in a center station (CS), such as modulation/demodulation and weight controllers.…”

We propose utilizing a radio-over-fiber technique of optical subcarrier-multiplexing transmission for radio base stations (BSs) with adaptive array antennas. The proposed system can be constructed at low cost since only one optical transmitter and receiver is required for a center station and a BS. Moreover, relative phases among antenna branches are insensitive to equivalent length fluctuation of an optical fiber.Index Terms-Land mobile radio equipment, microwave antenna arrays, optical fiber communication, phase-locked loop, subcarrier multiplexing.
