Abstract :
A two stage acquisition scheme for IR-UWB has been proposed to reduce the acquisition time of the spreading sequence. It has been shown that the performance of this scheme is better than that of the conventional scheme on AWGN channel. In this paper, the proposed scheme is investigated on the channel models of IEEE 802.15.4a. It is shown through the computer simulation that the proposed scheme can still reduce the acquisition time
