The impact of ultrawideband emissions on cdma2000 forward link performance

We present analytical models that quantify the increase in forward traffic channel power allocation for the cdma2000 forward link in the presence of a single noise-like UWB interference source. Our analysis shows that protection of the cdma2000 forward link for indoor reception requires: (1) lowering of the UWB indoor emission limit to be below -73.3 dBm/MHz when the UWB transmitter is within 1 m of the victim handset; or (2) operating the UWB device at a minimum separation of 5 m from the victim handset when it transmits at the indoor emission limit of -53.3 dBm/MHz.
