Abstract :
A synchronization scheme for impulse radio (IR) UWB receiver based on Trigg and Leach detector was proposed in this paper. The analysis revealed that additional gain of 5dB ~ 10dB was achieved with the proposed scheme. For example, to achieve the specifications of detection probability Pd ges 0.8 and false alarm probability Pfa les 10-6, the conventional matched filter (MF) based scheme requires SNR of 15dB, while only 5dB is needed for the proposed scheme. The performance of the proposed scheme was further verified by simulations
