In this paper, an ultra wideband (UWB) receiver is proposed based on optimally combining of multiple minimum mean square error (MMSE) detector outputs. These outputs are obtained by applying shifted observation windows. On one hand, each MMSE detector uses smaller number of taps and can be trained separately. This makes the combined structure suitable for adaptive filter bank implementation and for parallel processing. On the other hand, the system performance is effectively improved by diversity combining. The analysis and simulation results show that the combined MMSE receiver is capable of very high data rate transmission based on IEEE 802.15.3a channel model recommendation (J. Foerster)
