A possible concept of how present radiated emission standards could be amended in order to protect digital communication services

Present radiated emission standards are developed to protect analog communication services. Finding a new detector for electromagnetic interference (EMI) measurements with adequate weighting properties to quantify the effect of disturbance on digital communication services, is one important issue in the evolution of present radiated emission standards in order to protect digital communication services. Recent measurement and simulation results indicated that the RMS detector exhibits a response that can be correlated to the interference impact on digital communication systems that do not use error-correcting codes, or codes of block or convolutional type. In this paper, we show that this conclusion is also valid for systems using the more complicated concatenated codes. The codes investigated so far cover a representative and relevant selection of codes employed in practical digital systems. Therefore, the proposed concept to amend existing radiated emission standards is considered valid.
