A SYNCHRONIZATION APPROACH BASED ON CMHP FOR UWB SYSTEM
A novel set of pulses for UWB synchronization is presented in this paper. It is a linear combination of orthogonal modified Hermite pulses, which have unique advantages. The proposed pulses are orthogonal to each other and they can fit to the UWB spectrum mask. They occupy the most possibly similar frequency bands, which maximums the efficiency of spectra. They are applied to a parallel UWB synchronization approach, which takes use of parallel correlator to estimate the propagation delay. It can significantly shorten the processing time. Performance is investigated through the evaluation of mean-squared channel error for an AWGN channel and UWB indoor channel issued by IEEE 802.15.3a. It is observed that the parallel approach based on CMHP performs better than general method of synchronization.
