Bandwidth Efficient Hybrid Wireless-optical Broadband-access Network(WOBAN)Based on OFDM Transmission
In this paper,a simple and bandwidth efficient hybrid wireless-optical broadband access network(WOBAN)based on orthogonal frequency division multiplexing(OFDM)is proposed and designed.It is an optimal combination of an optical backhaul and a wireless front-end for an efficient access network.The bandwidth efficient WOBAN based on OFDM provides an effective solution to eliminate intersymbol interference(ISI)caused by dispersive channels.There are two factors considered important here; multipath fading in wireless link and dispersion effects in fiber link.The physical layer performance is analyzed in terms of bit error rate(BER),error vector magnitude(EVM),and signal-to-noise ratio(SNR).An 8 Gb/s data rate has been achieved by the optical backhaul along optical fiber length of 20 km.The wireless front-end access point supports data rate up to 240 Mb/s along an outdoor wireless link.
