Abstract Ultra Wide-Band(VWB) communication is the focus of the research of wireless communication. Impulse radio (IR)is one of the most important technology of UWB with data rate higher than 100Mbps and it has ultrawide frequency span and ultra low power spectra density. The timing recovery and pulse synchronization are the most critical problems of IR. In this paper, anovel mechanism based on orthogonal decomposition is proposed for joint timing recovering and multi-path components detection. Simulation shows that the algorithm has good performance on multi-path components detection, pulse repetition period estimation and timing recovery in dense multi-path environment with heavy ISI.
