چکیده
We have developed an all-optical fiber link antenna measurement system for a millimeter wave 5th generation mobile communication frequency band around 28 GHz. Our consists of optical electrical signal transmission system, antenna-coupled-electrode electric-field (EO) sensor GHz-band as receiving and 6-axis vertically articulated robot with arm length 1 m. can transmit the more than 40 GHz -30 dBm output level. EO receive from 27 to 30 In addition, we estimated far field factor using amplitude center modified estimation equation. The is 83.2 dB/m at

Millimeter-wave Radio over Fiber System for Broadband Wireless Communication
The wireless networking has attracted much interest in past decades, owing to its high mobility. People can connect their devices such as PDAs, mobile phones or computers to a network by radio signals anywhere in home, garden or office without the need for wires. The global growth of mobile subscribers is much faster than wireline ones, as the Figure 1 shows (Yungsoo et al., 2003). The number o...
متن کامل146-GHz millimeter-wave radio-over-fiber photonic wireless transmission system.
We report the experimental implementation of a wireless transmission system with a 146-GHz carrier frequency which is generated by optical heterodyning the two modes from a monolithically integrated quantum dash dual-DFB source. The monolithic structure of the device and the inherent low noise characteristics of quantum dash gain material allow us to demonstrate the transmission of a 1 Gbps ON-...

متن کاملDWDM millimeter-wave radio-on-fiber systems
We describe some of our recent results on DWDM mm-wave radio-on-fiber (RoF) technology for future broadband wireless systems. A supercontinuum (SC) light source is a promising multiwavelength light source for the system with photonic up-conversion. Multiplexing and demultiplexing schemes for optical frequency interleaving in order to extend the number of antenna base stations can be constructed...
متن کاملNetwork Coding Applications for 5G Millimeter-Wave Communications
The millimeter-wave bands have been attracting significant interest as a means to achieve major improvements in data rates and network efficiencies. One significant limitation for use of the millimeter-wave bands for cellular communication is that the communication suffers from much higher pathloss compared to the microwave bands. Millimeter-wave links have also been shown to change rapidly, ca...
