摘　　要：C-RAN架构通过基带集中处理、协作式无线电技术和实时云计算,有效实现无线接入网的绿色高效并面向未来平滑演进。C-RAN将BBU集中化,使得BBU协作化以应对潮汐效应、节省传统基站的机房和空调资源,达到节能减排的目的,现已成为业界研究和关注的热点。而决定C-RAN能否应用于现网的关键技术之一是C-RAN的传输技术。深入分析了光纤直驱、OTN/WDM、Uni PON等现有C-RAN传输技术,从光缆网架构和传输系统的角度出发,提出了原子波分解决方案。Based on centralized processing through baseband, col aborative radio technology and real-time cloud computing, C-RAN ar-chitecture can effectively realize the green and efficient radio access network and future-oriented smooth evolution. C-RAN, the BBU centralized, has al owed BBU arrangement to cope with a tidal effect, save area resources and air conditioning of tradi-tional base to realize energy conservation and emissions reduction, has become a hot topic in industry. C-RAN transmission technology can decide whether C-RAN can be used to current network. It analyzes optical fiber, OTN/WDM and UniPON, pres-ents the solution on atomic wavelength division from the aspect of cable network architecture and transmission system.
