本文介绍了一套基于PXI总线的半实物仿真系统的设计与实现,该系统用于验证某数据传输系统在满载荷工作的情况下用户数量对多址干扰的影响。经过仿真试验,该半实物仿真系统完全能够模拟数据传输系统在多用户情况下的多径干扰情况,并得出了产生多径干扰时的用户终端数量。试验验证表明。该半实物仿真系统达到了设计要求。

In this paper a hardware-in-the-loop simulation system based on PXI interface is introduced, and this hardware-in-the-loop simulation system is designed for testing the ability of suppressing multiple access interference which one data transmitting system is running when all users work. After the simulating experience, this hardware-in-the-loop simulation system is capable of simulating the data transmitting system when the multiuser work at the same time, and we get the quantity of terminal user when multiple access interference produces by using the hardware-in-the-loop simulation system. The experience shows that the hardware-in-the-loop simulation system reaches the requirement of designing.
