Clock synchronization is a crucial issue in the operation of wireless sensor networks. Although the existing synchronization algorithms under linear clock model assumptions perform well for short periods, they will become problematic for applications with long-term requirements. In this paper, we consider a more realistic and flexible relationship model for(More)
A low-complexity correlation based symbol timing synchronization (CBTS) algorithm for UWB MB-OFDM systems is presented. The correlation based scheme attempts to locate the start of the FFT window during frame synchronization sequence (FS) of the received preamble by firstly correlating the received samples with known training samples and then identifying(More)
An ultra-wideband channel is expected to exhibit different delay characteristics in different bands. In this paper, wideband channel delay characteristics are studied and delay parameters are found considerably different over frequency bands 3.1-4.6 GHz. Based on this observation, an adaptive timing synchronization scheme (ATS) which estimates and maintains(More)
A low-complexity correlation based symbol timing synchronization (CBTS) algorithm for UWB MB-OFDM systems is presented here. The scheme attempts to locate the start of the fast Fourier transformation (FFT) window during frame synchronization (FS) sequence of the received preamble by firstly correlating the received samples with known training samples and(More)
