| Abstract: | In this paper,we propose a receiving system for impulse radio ultra-wideband (IR-UWB) communications,in which the data and reference pulses are combined as one signal to transmit,and the received signal can be divided into the data and reference pulses in the receiver end using the energy concentration property of Chirp pulses in fractional Fourier transform (FrFT) domain.A detailed theoretical analysis of the proposed system is given,and the formulation of bit error rate (BER) is obtained.Then according to... |
