Ultra wideband (UWB) vehicular radar has been studied and developed to achieve a safe driving and to promote business in an intelligent transport system. In the paper, we propose a UWB radar pulse design method that makes use of a linear multi-pulse combination of wavelet pulses which satisfy the Federal Communications Commission (FCC) regulation. Simulation results show that the UWB pulse obtained...
A novel pulse design method for ultra wideband (UWB) communication is presented. The Gaussian pulses with the diverse variance factors are randomly selected as basis functions. The corresponding power spectral density (PSD) of linear combination pulse which complies with Federal Communications Commission (FCC) regulation is obtained by adjusting the parameters such as variance and the value of the...
UWB vehicular radar has the potential to be a powerful tool in improving vehicle safety. The Gaussian monocycle pulse, commonly used in the UWB vehicular radar system, can not satisfy the bandwidth constrains. So a new pulse shape based on wavelet is presented, which selects factors of Morlet wavelet to meet the FCC spectral mask by searching the peak frequency which lies in bandwidth between 22 and...
