| 摘 要： | 虚拟暗室的测试理论是用于普通环境下的EMI测试的新方法，它的基础是自适应噪声抵消系统。本文设计一种改进的自适应噪声抵消系统，通过添加较大额外噪声的方法，有效地解决实际测试时由于存在信号串扰的而导致的输出信噪比不合理的问题。利用LabVIEW和MATLAB编写相应的RLS自适应算法程序并进行了仿真实验，结果表明这种改进算法比标准的方法可得更佳的信噪比。 |

| Abstract: | Virtual chamber theory describes a new method used to test equipment's EMI in normal environment that is based on adaptive noise cancellation system.An improved noise cancellation system with additional noise as input is introduced that can effectively resolve the problem of signal crosstalk during actually EMI testing.RLS adaptive algorithm program is chosen and designed with LabVIEW and Matlab.Simulations show considerable improvement in output signal-to-noise ratio is obtained comparing with standard noi... |
