Software radio architecture based on general PC and network

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.
