In this paper, we proposed an improved mobile fronthaul architecture employing the SNR-
improved delta-sigma digitization scheme and 4-level pulse amplitude modulation (PAM-4) …

All-digital radio-over-fiber (RoF) transmission has attracted a significant amount of interest in
digital-centric systems or centralized networks because it greatly simplifies the front-end …

The fifth generation (5G) cellular network is expected to include the millimeter wave
spectrum, to increase base station density, and to employ higher-order multiple-antenna …

To achieve the massive device connectivity and high data rate demanded by 5G, wireless
transmission with wider signal bandwidths and higher-order multiple-input multiple-output …

The terahertz (THz) frequency bands are being explored as a potential means of enabling
an ultra-high transmission capacity in sixth-generation (6G) radio-access networks (RAN) …

For the fronthaul link in the fifth-generation (5G) wireless networks, optical fiber is one of the
most widely used medium, owing to its large bandwidth and low transmission loss. However …

This paper presents a solution for enabling the coexistence of digitized radio-over-fiber (D-
RoF) and analog radio-over-fiber (A-RoF) interfaces operating in the optical fronthaul of 5G …

For the first time, we demonstrate in this paper an intensity-modulation direct-detection
(IMDD) universal filtered multi-carrier (UFMC) system through several hundred meters of …

Analog radio-over-fiber transceivers allow a substantial reduction in the complexity of the
remote radio heads in the wireless network of the future. In this letter, we discuss the …

This paper proposes and experimentally demonstrates an ultra-high order signal security
enhancement method based on delta-sigma modulation (DSM). We employ a radial basis …
