B3G无线蜂窝试验系统以空中接口峰值速率达到100Mbps为目标。对于物理层能够提供这样高速率的通信系统,需要有相应的高速业务来验证。文章主要讨论B3G无线试验系统软件研究与实现,其中的关键技术包括:为了节约CPU资源的零拷贝操作设计,为了提高空中接口资源的利用率而采用的裸包设计,以及为了实现数据包可靠传输而采用的链路级差错控制机制设计。
B3G wireless cellular test system to the air interface peak rate of 100Mbps as the goal. For the physical layer to provide such a high rate of communication systems, the need for the corresponding high-speed business to verify. The article mainly discusses the research and implementation of B3G wireless test system software. The key technologies include the design of zero-copy operation for saving CPU resources, the design of bare package for improving the utilization of air interface resources, and the implementation of reliable data packet transmission The link-level error control mechanism used in the design.
