This paper demonstrates the performance of a multiband impulse radio architecture with a non-coherent energy detection receiver in the IEEE802.15.3a channel model. Frequency dependent attenuation due to free space path loss lead to a significant performance degradation of any UWB system. The flexibility of the multiband impulse radio architecture in conjunction with a dynamic subband deactivation algorithm allows to fight this performance degradation. Furthermore an approximated log-likelihood ratio calculation for a non-coherent energy detector is introduced. Link budget calculations show the performance of different configurations of the proposed architecture.
