MB-OFDM UWB signal co-transmission with WCDMA, WLAN and GSM over multi-mode radio-over-fiber

In this paper, the performance of Multiband - Orthogonal Frequency Division Multiplexing (MB-OFDM) Ultra WideBand (UWB) signal over a multimode fiber based radio-over-fiber (ROF) link is discussed. Co-transmission of UWB signals with other wireless signal standards including W-CDMA (2.15 GHz), WLAN802.11a/g, and GSM (1.8 GHz) are considered. Based on the measurement results, it has been shown that UWB signals can be transmitted without error over 400 meters for the highest data rate of 480 Mbps using the system proposed. Co-transmission can also be successfully done with minimal mutual interference.
