Bit and power loading for the multiband impulse radio UWB architecture

In this paper we present two different bit and power loading algorithms for the non-coherent multiband impulse UWB architecture. The first one is a very simple threshold based bit loading algorithm and an extension of the detect and avoid (DAA) algorithm presented in [1]. The second one is a more powerful algorithm, enabling also power loading. These algorithms allow a more efficient and flexible spectrum use, higher data rates and use less transmission power. The bit error rate performance is significantly improved. Both algorithms support inherent powerful DAA.
