Unwanted emissions of digital radio systems

In this Report, measurements of the unwanted emissions of a number of equipment samples of digital radio systems are presented and compared with: 1) the OoB emissions limits in Recommendation ITU-R SM.1541, regional agreements, and/or publications of Standards Development Organisations (SDOs); 2) the spurious emissions limits in Recommendation ITU-R SM.329, ERC/REC 74-01, and/or publications of Standards Development Organisations (SDOs).

The boundaries of the modulation-based unwanted emissions in these measurements are compared with the limits for the boundary between the out-of-band (OoB) and spurious domains from ITU-R publications.
