光纤水听器信号相位载波解调的集群实现
摘要
光纤水听器信号的PGC解调算法是一个较为复杂的过程
随着光纤水听器向大规模阵列方向发展
对信号传输及处理容量提出了越来越高的要求。在LINUX系统中搭建了一个由3台计算机组成的小型集群
并将集群运算应用于光纤水听器信号PGC解调
实验结果表明:该集群系统的性能是单台计算机性能的2倍多
大大提高了信号的处理速度
是未来大规模光纤水听器信号处理的重要选择方案之一。
Abstract
Phase-generated carrier(PGC)demodulation arithmetic of the fiber-optic hydrophone signal is a complicated process.With the development of fiber-optic hydrophone towards large-scale array
there is a big requirement for signal transmission and processing.A cluster computing project has been put forward
and an experimental PC cluster made by 3 Pentium IV computers has been set up in LINUX system.The result indicates that the capability of the cluster is two times stronger than the capability of single computer.The cluster greatly enhancs the rapid of signal processing
and is one of the important project of the signal processing of the array fiber-optic hydrophone in the future.
