Sensitive and non-sensitive DVB-T mask for coordination with IMT-advanced systems

As a result of frequency spectrum scarcity and emerging various wireless applications, coexistence and sharing between wireless systems become a recently significant issue. At WRC-07, 790-862 MHz is allocated for IMT-Advanced systems on a co-primary basis in company with existing digital video broadcasting- terrestrial (DVB-T). Therefore, coexistence and sharing requirements must be achieved in terms of both co-channel and adjacent channel frequencies. Coexistence situation is analyzed by using sensitive and non-sensitive spectral emission mask (SEM) of DVB-T. Possible intersystem interference mitigation techniques are recommended.
