Power Optimization With BLER Constraint for Wireless Fronthauls in C-RAN

IEEE Communications Letters, 2016
Cloud radio access network (C-RAN) is a novel architecture for future mobile networks to sustain the exponential traffic growth thanks to the exploitation of centralized processing. In C-RAN, one data processing center or baseband unit (BBU) communicates with users via distributed remote radio heads (RRHs), which are connected to the BBU via high ...
