Abstract :
Ultra-wideband (UWB) signaling is an emerging technology that promises high data rates at a very low power cost. Due to the complex characteristics of the UWB channel, the signal processing required to achieve high data rates even at low distances is very large. In this paper, the complexity trade-offs associated with three elements of the digital baseband: the correlators bank, the RAKE receiver, and the Viterbi based MLSE equalizer, are presented for a practical transceiver.
