In this paper, a novel rapid synchronization algorithm is proposed for UWB systems with noncoherent receivers based on an energy capture scheme, fully exploiting adequate multipath component. Only one symbol observation is required to acquire synchronization, which speeds up the overall synchronization process. And the lower complexity is achieved via not(More)
In this paper, a novel quasi-4PPM modulation is presented firstly for UWB systems, and then the corresponding synchronization and demodulation schemes are proposed. Due to the nature of the unique signal structure, the information bits are transmitted and demodulated by twos, which doubles the transmission efficiency compared with conventional existing(More)
