Radio-over-fiber (RoF) based fiber-wireless (Fi-Wi) networks have received increasing attention for their ability to achieve high spectral efficiency and macroscopic coverage for high speed multimedia services envisioned by future broadband communication systems. However, a major issue associated with this appealing technology is that multipath dispersion of the wireless channel coupled with the nonlinear distortion (NLD) of the RoF link significantly degrades the system performance. In order to counteract the effects of these distortions, estimation and subsequently equalization, of the concatenated Fi-Wi channel need to be performed. In a multiuser environment, multiple access interference (MAI) poses another challenge to the tasks of channel estimation and equalization. Against this background, this thesis explores improved channel estimation techniques for the uplink of RoF based Fi-Wi networks and three novel techniques have been proposed.
