To meet the enhanced-mobile-broadband (eMBB) challenges in 5G, we have systematically explored the potential of the photonics-aided millimeter-wave (mm-wave) communication in terms of the wireless transmission capacity and distance it can accommodate. Enabled by various kinds of advanced multiplexing and digital-signal-processing (DSP) techniques, we have successfully achieved the significant enhancement of the wireless mm-wave signal transmission capacity from 100 Gb/s to 400 Gb/s, even to 1 Tb/s. Since our large-capacity (>100-Gb/s) experimental demonstrations typically have a very short wireless transmission distance of several meters, we have further explored the techniques for the extension of the wireless mm-wave signal transmission distance, and successfully achieved a series of field-trial demonstrations on photonics-aided long-distance (>100-m) wireless mm-wave signal transmission. We have realized the record-breaking product of wireless transmission capacity and distance, i.e., 54 Gb/s × 2.5 km.

用于 5G 中极端移动宽带通信的光子辅助毫米波技术

为了应对 5G 中的增强型移动宽带 (eMBB) 挑战，我们系统地探索了光子辅助毫米波 (mm-wave) 通信在其可容纳的无线传输容量和距离方面的潜力。在各种先进的多路复用和数字信号处理（DSP）技术的支持下，我们成功实现了无线毫米波信号传输容量从100 Gb/s显着提升到400 Gb/s，甚至到1 Tb/s的显着提升。 s。由于我们的大容量（>100-Gb/s）实验演示通常有几米的非常短的无线传输距离，我们进一步探索了扩展无线毫米波信号传输距离的技术，并成功实现了一系列光子辅助长距离（>100米）无线毫米波信号传输的现场试验演示。我们实现了无线传输容量和距离的创纪录产品，即54 Gb/s × 2.5 km。
