Generation and analysis of convergent vortex wave based on orthogonal waveform Open
Electrogenic vortex wave refer to the wave that carry orbital angular momentum (OAM) in the radio frequency (RF) domain. The OAM mode is expected to be initially explored and applied as a full novel spatial dimension resource. However, the…

Broadband dual-channel channelizer based on a microwave photonic power tunable image rejection down-conversion Open
Radiofrequency (RF) channelization has potential high frequency and wideband advantages in frequency-domain channel segmentation and down-conversion reception. In this paper, we propose a compact dual-channel channelizer that can process h…

DC Restoration by Data-Aided Sequence in Kramers-Kronig Receiver Open
In recent years, Kramers-Kronig (KK) receiver has been widely studied because of its simple structure and the ability of digital signal processing (DSP) to recover complex value signals. One practical structure is detecting the optical sig…

Data-aided channel equalization scheme for FAST radio over fiber transmission system Open
The Five-hundred-meter Aperture Spherical radio Telescope (FAST) located in Guizhou, China, is a very sensitive single dish telescope. Due to the large size of the telescope, optical fiber is used for the transmission of the 3-km astronomi…

Generation of rotational orbital angular momentum beams in the radio frequency based on an optical-controlled circular antenna array Open
The orbital angular momentum (OAM) has been widely used in the wireless short-range communication system, but for long-distance communication, the huge difficulty of beam receiving is a great challenge. In this paper, to overcome this chal…

Secure Transmission of Radio Orbital Angular Momentum Beams Based on the Frequency Diverse Array Open
The circular phased array is one of the main methods to generate radio frequency orbital angular momentum (RF-OAM) beams with high purity and capability of OAM-beams steering, but OAM beams generation and steering are only related to angle…

Analog radio of fiber link of 2-Gbaud OOK/BPSK radio frequency-orbital angular momentum beam transmission over 19.4 km Open
The 5G mobile communication system provides ultrareliable, low-latency communications at up to 10 Gbps. However, the scale and power consumption of 5G is tremendous owing to a large number of antenna drivers required by the massive multipl…
