In this paper, we investigate the performance of OFDM and FBMC signals after being transmitted over a seamless fiber-wireless fronthaul system. We also examine the performance of OFDM signals using different multiple radio access techniques after being transmitted over the seamless system. We confirm that the fronthaul system has significant impacts on the performance of the signal waveforms and multiple...
This paper reviews our recent research activities on seamless fiber-wireless systems for future mobile networks, including: radio-on-radio-over-fiber; signal processing-aided multiple signal transmission; high-capacity seamless system; and simultaneous power- and radio-over-fiber.
This presentation reviews radar systems with many antenna units connected by optical networks, which distribute waveforms of wideband frequency modulated millimeter-wave signals, where the range resolution can be a few centimeters.
This paper reviews seamless networks based on radio-over-fiber (RoF) technology. We focus on train communication networks (TCNs) consisting of optical networks and many radio access units (RAUs). Waveform for radio communications can be effectively delivered to each RAU by RoF. The TCN can be controlled by train location information to reduce overhead due to hand-over in mobile communication systems.
We propose a flexible and high-performance fronthaul system for future mobile networks using a seamless combination of fiber-optic and millimeter-wave (MMW) systems. The proposed system employs a high-quality optical MMW signal generation at the transmitter and a stable and high-performance MMW self-homodyne detection at the receiver. In the downlink direction, successful transmission of intraband...
Wired and wireless seamless networks comprised of optical-fiber and radio-wave links can provide high-speed, resilient, and flexible broadband services, one of the important requirements for which is the precise and high-speed control of light waves based on advanced photonic technologies such as digital coherent detection, high-speed electro-optic conversion, and radio-over-fiber. In this paper,...
