A low-complexity distributed-MIMO testbed based on high-speed sigma-delta-over-fiber

Distributed multiple-input-multiple-output (DMIMO) is a very promising technique to improve capacity and quality of service for emerging 5G systems. In this paper, we propose a flexible and low-cost testbed for D-MIMO systems, where a sigma-delta over fiber (SDoF) solution is proposed to address the fundamental challenge of phase-coherent transmission between multiple distributed access points (AP...
