%X The code acquisition is an important issue of DS-UWB system design.Because the MAXimum selection/Threshold Comparison(MAX/TC) criterion for code acquisition has good performance in DS-UWB system,in this paper,a MAX/TC criterion for code acquisition algorithm using the information of the auxiliary sequence,which can be used to reduce the acquisition time of the coarse Pseudo-Noise(PN) sequences,is presented.Then the theoretical analysis is given and simulation tests of proposed acquisition algorithm are carried out in UWB indoor channel environment.The simulation results show that with the proposed algorithm,the mean acquisition time can be reduced considerably while the acquisition performance is maintained.
