In this paper, the authors address a problem of spectrum sharing and coexistence between Long Term Evolution (LTE) systems and Digital Video Broadcasting-Terrestrial (DVB-T). Previous studies have shown that coexistence of LTE and DVB-T without protection guard may cause interference. However by applying Cognitive Radio (CR) access technique, the probability of interference will decrease and the available spectrum can be used more efficiently. The main objective in spectrum sensing in a given band is to optimize the performance of the LTE as secondary network. This performance can be tested using a statistical analysis tool incorporating Monte Carlo and Spectral Emission Mask (SEM) technique.
