Frequency Domain UWB Receiver Instead of Low Complexity Rake Receiver

The extremely high speed offered by UWB systems allows the guard band to be extended to 100% instead of maximum of 25% as in broadband systems. This particular guard ensures the clearness of this channel completely from the spurious signals before transmitting next symbol. In this paper, the performance of non-block transmission frequency domain UWB receiver with changeable zero-padding is presented. The receiver can be an alternate to Rake receiver, since clustering effect, common in UWB signals makes Rake receivers impractical and claims low complexity rake receivers, but they are not optimum, either.
