4.4. Interference to Cellular Systems
In this section, we discuss UWB interference to CDMA-based cellular systems. The discussion is based on calculating the maximum UWB PSD that degrades the performance of a cellular receiver by M dB. Equation 4-14 defines the amount of UWB PSD, Gp, that increases the victim receiver's noise power by a margin of M dB.
Equation 4-14
where M denotes the amount of SNR degradation in dB, k is the Boltzmann constant, T is the temperature in Kelvin, and the denominator represents the cumulative interference from multiple UWB sources. The derivation of this equation is available in Appendix A.
The interference analysis ...
