基于通用计算机和网络的软件无线电结构

Software radio architecture based on general PC and network

采用通用化设备实现软件无线电平台可以使软件无线电技术更为通用化 ,同时具有可实现性。根据目前通用计算机和网络设备发展迅速 ,性能不断提高的趋势 ,提出一种由计算机和网络构成的软件无线电平台的结构。用网络连接计算机构成机群 ,用消息传递实现计算机间的互联 ,通过采用一种协同计算方案解决其关键技术和实现机制问题。这些技术为软件无线电平台提供了充足的性能 。

Using general purpose platforms and software modules instead of application specific hardware can facilitate application of the software radio technique using computer and network based architceture. A novel distributed computing protocol is used to controll communication traffic and computation so that the cluster of general purpose computers can be interconnected by an ethernet. The system can then handle a real time data stream. The novel high speed message passing mechanism is used to construct a high performance platform ideal for software radio, which is scalable and flexible.
