Abstract:
This paper presents adaptive cancelation techniques to suppress ambient noise in electromagnetic interference measurements on open area test sites. The measurements are carried out in time-domain to reduce the total measurement time. To achieve optimum cancelation, time-domain as well as frequency domain adaptive filter algorithms have been investigated and compared in respect of their suppression performance. An advanced digital signal processing technique for fast measurements of electromagnet...     »
