Abstract: Aiming at receiving problem of high-rate signals, this paper proposes a communication receiver system based on cluster computing, the hardware and software architecture, the key technologies of the system are introduced, including high-speed A/D conversion, parallel data dispatching, efficient load-balance algorithm, gigabit Ethernet even output 155 Mb/s, and supporting for heterogeneous nodes and parallel processing of different kinds of signals. Practical tests show that the receiver can work at a sample rate up to 100 MSPS, a network dispatching rate up to 200 Mb/s and a signal bandwidth up to 40 MHz and can receive various high-rate communication signals in real-time.

Key words: software radios, cluster computing, load balance, gigabit Ethernet
