Part of the Series on Integrated Circuits and Systems book series (ICIR)


The ability to optimally exploit the 7.5 GHz of newly created nlicensed spectrum for UWB technology depends on addressing a number of challenging system design issues. This chapter provides an overview of many of these issues and some technical trade-offs and comparisons with different system designs. Some of the challenges include dealing with multipath propagation, energy capture, narrowband interference, rapid synchronization, and varying regulatory rules throughout the world, just to name a few.
