Multiband Approach to UWB 181
low, especially where low PRF systems are contemplated, it is possible to work
well within this peak-to-mean ratio limit and, thus, to limit the interference
potential to values significantly lower than those anticipated by the original
FCC Report & Order, such that widespread deployment of multiband UWB
devices can have a negligible impact on existing services.
In order to quantify the first item in the above discussion, we can directly derive
the average BER for a QPSK victim service under the influence of interference from
a multiband UWB system with a duty cycle of ...
