LU Guang-jun, Zhang Li, Pei-Zhong Lu · 2010
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.
