Abstract

The FDSS macrocell downlink capacity is evaluated for macrocells that operate at the same frequency of the ATSC 8-VSB Digital TV station and that is nearby the DTV installations. It has been found that the cell capacity vanishes for a very little distance from the 8-VSB transmitter and that the critical distance is of 22 km from the 8-VSB transmitter. It has been shown that the critical distance increases with the increment of the effective transmitted power of the TV transmitter and with the increment of the TV transmitting antenna. Moreover, it has been noticed that the effect of the 8- VSB system is null at a distance of 60 km and that the downlink vanishes at the zone very near to the 8-VSB installations
