摘要
IP是移动通信的最新发展方向,世界主流通信设备制造商大多采用了全IP平台技术。文章对CDMA2000 1xEV-DO调制解调模块展开了研究,提出了一个基于IP的基站调制解调器的实现方案,设计了媒体流IP和控制流IP分离平台以体现NGN网络中控制与业务分离的理念,剖析了基于高通CSM5500芯片组的调制单元、解调单元、Turbo解码单元的原理和结构,并对这3个单元之间的通信接口进行了详细分析。
IP is the newest direction of mobile communication, the mainstream communication equipment manufacturers on earth, mostly use All-IP platform technology. The author studies the modem module in CDMA2000 lxEV-DO system, and presents a design of cell site modem based on IP, and describes the separate communication platform for media stream IP and controlling stream IP ,which could satisfy such idea as separating control from service in NGN network, then analyzes the principle and structure of modulator element.demodulator element and turbo decoder element based on qualcomm CSM5500 chipset , finally discusses the communication interfaces among these three elements.
