Impact of Ultra Wide Band (UWB) on Digital Audio Broadcasting (DAB) and Digital Television (DTV) Systems

Inhalt:
The effect of the UWB transmitters on the digital television cell range is studied. The effect of the UWB transmitters on the DAB receiver (with a set-top antenna) performance is studied. It is shown that the DAB receiver can not tolerate an UWB power density of -90 dBm/MHz when the separation between the UWB transmitter and the DAB receiver is 1 m at DAB frequency of 1465 MHz. It is noticed that the DAB receiver can tolerate an UWB power density of -105 dBm/MHz even if the separation is less than 1 m for DAB frequency of 200 MHz. It is shown that, the DTV receiver can not tolerate an UWB power density of -96 dBm/MHz when a separation between the UWB transmitter and the DTV receiver is 1 m at DTV frequency of 500 MHz.
