- Abstract:
- Non-linearity in the ISDB-T transmission chain causes intermodulation products that widens the spectrum emission and should be taken into account to assign frequency channels. The characterization of the transmission spectrum mask is one of the most important measurements in order to achieve the best use of the electromagnetic spectrum. The use of critical mask defined in [1] allows allocations of co-site adjacent channels for anefficient use of the electromagnetic spectrum that is a finite and limited resource. In this paper different test procedure using spectrumanalyzer and dedicated digital TV analyzer in order to measure the ISDB-T transmission maskis discussed.
