英文摘要:With the rapid development of wireless communication systems, different standards have begun to be merged. Operators place stringent requirements on reducing OPEX and CAPEX, and as a result, soft base stations supporting multiple standards have become preferred. This paper introduces the background of soft base stations, then analyzes architecture design, system modules, and key technologies. It suggests the future development of soft base stations will tend towards more integrated, flexible deployment of resource baseband; abundant transmission, lower cost, and energy efficiency.
