Digital Signal Processing for High-Speed Fiber-Wireless Convergence [Invited]

Journal of Optical Communications and Networking, 2018
We review recent advances in the field of fiber-wireless convergence to better support cloud radio access networks via high-speed low-latency mobile fronthaul between remote radio units and baseband units. We also present how digital signal processing (DSP) may be used to support both common public radio interfaces (CPRI) in a point-to-point ...
