This paper innovatively proposes an indoor wireless propagation model in WiFi radio-over-fiber network architecture for received signal strength (RSS) based localization in the Internet of Things. The proposed model adds attenuation terms of obstacles in each sub-space by dividing the room into several sub-spaces according to the obstacles' distribution. The influence of obstacles in sub-space on...
This paper, for the first time to our knowledge, introduces a power control technique for radio-over-fiber (RoF) downlinks in frequency division multiplexing (FDM) cellular communication systems. The power control technique, which has been widely used in traditional wireless systems, is to radiate sufficient power to establish an adequate service for a particular distance. Due to RoF link nonlinearities,...
This paper presents our recent progress on advanced radio-over-fiber (ROF) technologies for in-building optical-wireless access networks, including multi-service, full duplex and polarization diversity ROF systems design, and experimental delivery of uncompressed HDTV signals. The novel polarization diversity technique is proposed to improve receiving sensitivity and increase anti-interference capacity...
A novel scheme of 2.5 Gb/s optical PSK signals transmission and ASK wireless signals generation with 15 GHz carrier based on heterodyne detection is demonstrated, which can realize polarization diversity and provide 1.3 Gb/s HDTV applications.
