“…In a wireless communication system, with the explosive demand for bandwidth growth, wireless carrier frequency migrates to a higher millimeter-wave band has become an inevitable trend [2,3]. V-band in the 57-64 GHz range with 7 GHz free license bandwidth has been considered an ideal band for high-capacity data transmission, multiGb/s wireless access.…”

Abstract-In this paper, we propose a novel architecture of full-duplex millimeter-wave radio-over-fiber (RoF) system based on polarization division multiplexing (PDM) and wavelength division multiplexing (WDM) technology. In our scheme, the light waves for downlink and uplink transmission are provided by the same laser, which realize the source-free base station (BS) and multi-services transfer for next generation wireless access network. Since the uplink optical carrier is Y -polarized light wave which does not bear the downlink signal, no cross-talk from the downlink contaminates the uplink signal. At the BS, it is detected by a high-speed photoelectric diode (PD) to generate a 15 GHz intermediate frequency (IF) and a 63 GHz radio frequency (RF) signal. This reduces the system complexity and cost. The simulation with 2.5 Gbps NRZ signal transmission exhibits good performance both at 15 GHz (Ku-band) and 63 GHz (V-band).

“…In wireless systems with RoF technology, only radio frequency (RF) units connected to a central office are located in remote areas and the central office operates the PHY signal processing and MAC functionality [5][6][7][8][9]. The RF units, which are connected to the central office via an optical fiber, convert the optical signals to electrical signals before transmitting them over the radio channel, and vice versa.…”

“…An RoF-based access architecture for integrating multiple wireless systems was discussed in [8,9]. However, the integration of the conventional carrier sense multiple access with collision avoidance (CSMA/CA)-based wireless standard with an RoF-based architecture requires research because the long propagation delays in the optical fiber links may cause the CSMA/CA protocol to behave unexpectedly, resulting in a decrease in the system throughput.…”

In this paper, we propose a medium access control (MAC) protocol to allow a radio over fiber-based wireless local area network (RoF-based WLAN) to coexist with legacy carrier sense multiple access with collision avoidance (CSMA/CA)-based WLANs. In RoF-based WLANs, there are long propagation delays between access points (APs) and stations (STAs). When an RoF-based WLAN uses the conventional CSMA/CA protocol and coexists with legacy WLANs, the propagation delay causes unexpected frame collisions and unfairness between the RoF-based WLAN and legacy WLANs. The proposed protocol reduces unexpected frame collisions and improves fairness between the RoF-based WLAN and legacy WLANs in environments where they coexist. It is only necessary to apply the proposed protocol to the AP in the RoF-based WLAN (RoF AP); there is no need to modify STAs, which is an advantage of the protocol. In the proposed scheme, the RoF AP transmits frames during the transmission and reception of frames in the legacy WLAN, such that the frame transmitted by the AP arrives at a destination STA one short interframe space (SIFS) period after the channel became idle, and thus the RoF AP's frames do not collide with other frames. As a result, the proposed method decreases the likelihood of frame collisions and increases the throughput of the RoF-based WLAN. In addition, the proposed method provides adaptive adjustment of the transmission probability, which enables the RoF-based WLAN and the legacy WLANs to fairly share wireless channels. The proposed protocol has been investigated for IEEE 802.11a/b/g WLANs. Numerical analysis and simulation evaluations show that the proposed scheme increases the TCP throughput of the RoF-based WLAN up to the same level as that in legacy WLANs.
