- Los Angeles existing DTV station KMEX-TV, ch. 35, was selected. Tx2 and Tx3 are hypothetical. Transmitter parameters: KMEX-TV: 400 kW ERP, 98 m AGL, dir antenna pointing South-West ° Tx2: 10 kW ERP, 50 m AGL, dir antenna pointing West Tx3: 5 kW ERP, 50 m AGL, dir antenna pointing North-East Receiver parameters: Fixed: Field strength 41 dBuV/m, 90% service availability, antenna height 10 m Mobile: C/N+I = 15 dB, 90% service availability, antenna height 1.5 m Path Loss: CRC-PREDICT v3.21, elevation and Land cover data using Computamaps (500 m resolution) Echo cancelation: The equalizer values used for echo cancelation were -10 to 45 usec and 3 dB C/N+I diff., these values may need to be reviewed and would consequently affect the coverage slightly. Low power transmitter, combined with directional antennas and the terrain elevation (mountains) were used to limit self-interference. Addition of gap filler or coverage extender in the SFN needs to be done carefully, it is easy to cause self-interference, need for advance simulation tool for planning.
