This paper presents the use of a commercially available radio scanner for characterizing on-vehicle 2×2 Long-Term Evolution (LTE) radio Multiple-Input Multiple-Output (MIMO) antennas. The scanner measures the LTE eNodeB, i.e. the cell base station, reference signals and each channel and determines the MIMO channel matrices from which the downlink throughput can be determined. For a given LTE radio,...
A new approach to the precise expression of Bi-SAR point target reference spectrum is studied in this paper. The study shows that the two squint angles respectively from transmitter and receiver to the target have a kind of stable relationship during the process of aperture synthesizing, so the azimuth Doppler frequency can be divided into two parts: transmitter azimuth Doppler frequency and receiver...
Error-free data transmission at 8 Gbps in the 250-GHz millimeter-wave band over 0.5-m distance was demonstrated. A J-band uni-travelling-carrier photodetector (UTC-PD) module and an InP-Schottky barrier diode detector integrated with a slot ring antenna and an output low-pass filter were used for the transmitter and receiver, respectively. Taking the maximum available power from the UTC-PD module...
This paper presents photonic generation of high-power continuous terahertz-wave signals at frequencies from 300 GHz to 400 GHz, and their application to giga-bit wireless communication systems.
