Abstract

This paper investigates code synchronization for a recently proposed code-shifted reference (CSR) impulse radio ultra-wideband (IR-UWB) system. In the CSR scheme every symbol with the code-shifted information bits is conveyed by several frames and during each frame only one pulse is transmitted. By assuming that the start of each frame concerning the receiver's clock is known, two code synchronization algorithms are proposed to estimate the position of the first frame in each symbol and each algorithm works without using a preamble sequence. The performance of the two algorithms are evaluated under IEEE802.15.4a industrial line-of-sight (LOS) scenario. The simulation results reveal that the second algorithm with the partial Euclidean distance minimization outperforms the first algorithm with the direct searching. © 2010 IEEE.
