基于PXI平台的多级数BPSK伪随机码波形的生成

摘要

针对传统伪随机码设计复杂、开发周期长的问题,设计一种多级数BPSK调制的伪随机码波形生成系统.在深入分析伪随机码产生原理和性能特点的基础上,应用PXI模块、LabVIEW软件和VI工具包等设计工具进行系统设计.结果表明:该系统具有较强的灵活性和扩展性,可用于演示伪随机码的产生和用于验证引信的抗干扰性能.%In view of design complexity and long development cycle for traditional pseudo-random code, it is intended to design a multilevel BPSK modulation pseudo-random code waveform generation system. Based on deep analysis of generation principle and performance features, it executes system design by application of PXI module, LabVIEW software and VI toolkit. The results show that this system is equipped with strong flexibility and extendibility that can demonstrate the generation of pseudo-random code and validation for anti-interference performance of fuse.
