Abstract
Because of the norrow signal duty cycles, SYNC is the most critical issue in UWB-IR systems. Some synchronization schemes like a SD-IR-UWB receiver have been proposed to synchronize received signals rapidly. Yet, SD IR-UWB receiver is not suitable for operation in multi-user stiution because of MAI. By taking advantage of FD-IR-UWB receivers, we propose a PFD-IR-UWB receiver to do so. Our proposed PFD IRUWB receiver manifests better immunity against message passing interface and MAI than the SD IR-UWB. Based on this PFD IR-UWB receiver, search regions are limited to one frame duration without any symbol-level synchronization sheme. Performance of PFD and SD receivers are compared by simulations, showing that the proposed PFD receiver not only achieves significantbit error rate performance but also better and more robust results than the SD receiver in this paper
