A direct broadcast satellite system for the United States - DBS/FS frequency sharing

The possible interference from the Private Operational Fixed Service into direct broadcast satellite home receivers is considered. An evaluation is made of the three possible sharing alternatives: co-channel sharing, adjacent channel sharing (interleaving), and band segmentation. It is found that co-channel sharing is not feasible because of the unacceptably large number of households that would be affected. Adjacent channel sharing, although not as problematic as co-channel sharing, would still result in a significant number of households (7%) being subject to interference.
