We have experimentally demonstrated a world record of transmitting 60-GHz radio frequency signals over 200-km standard single-mode fiber (SSMF) through a novel end-to-end fiber-wireless integration and transport scheme using a low-cost directly modul

As a counterpart of analog radio-over-fiber technology, digital radio-over-fiber (D-RoF) system, such as common public radio interface (CPRI), is a matured and robust solution to support RF signal delivery in traditional mobile fronthaul networks. In

In this study, to the first time, we demonstrate an offset-QAM carrier-less amplitude and phase modulation (OQAM-CAP) technique for spectral efficient multi-user radio-over-fiber systems. In comparison with traditional QAM-based CAP modulation scheme

In this letter, we proposed a centralized pre-equalization mechanism in a fiber-wireless integrated mobile fronthaul system to compensate the channel degradation among multiple component carriers (CCs) with reduced complexity and cost at user termina

Design of power distribution networks (PDNs) in high speed digital circuit has become a more challenging task in view of decreasing supply voltages and increasing transient currents. The parasitic inductance of a PDN is the most crucial parameter tha

In 4G cloud radio access networks (C-RAN), latency at the mobile fronthaul was conceived mainly as a limiting factor of the fronthaul length. As long as fronthaul latency is not leading to violation of the hybrid automatic repeat request (HARQ) limit

Interchip communication on a multichip module or silicon interposer continues to rely on copper transmission lines. While very short reach optical communication is expected to provide advantage in bandwidth density, millimeter data transmission may o

We compared OFDM and filter-bank multicarrier (FBMC) with time-frequency modulation adaptation in a centralized fiber-wireless integrated mobile fronthaul system supporting 5G. Experimental results demonstrate that FBMC outperforms OFDM with higher t
