Optimal coexistence in the same frequency band of television and mobile radio services
Abstract
Mutual interference between the 174 to 230 MHz television band transmission and mobile communication transmissions by the SST technique is reviewed. Theoretical aspects of SST electronic subsystem development are considered. An emphasis weighting function technique applied to a frequency hopping SST system is analyzed and compared to the operation of frequency hopping in regions of the television frequency band which are less sensitive to interference. The characteristics of measuring systems adapted to the research needs of SST development are discussed.
