  • This paper gives a serial acquisition method which can be easily implemented in time hopping ultra-wide band system. Based on this method, the acquisition performance in the multiuser environment is analyzed, and the relationships between the detection probability, false alarm probability, detection threshold and average acquisition time are given. From the theoretical analysis and numerical simulation, it is noted that with the increasing of user number, the detection probability will decrease. By contrary, the false alarm and the detection threshold will increase accordingly, and the acquisition time will also increase from s to ms.
