Synchronization Estimation and Signal Acquistion for DS-UWB System
This paper presents a simply and fast method to realize UWB synchronization estimation and signal acquisition for DS-UWB system.Use of Ultra-Wideband technology with spread spectrum scheme will make a big effect to short range wireless network.UWB signal synchronization and fast acquisition is a big challenge for UWB wireless communication system realization.The transmitter-receiver synchronization and one signal acquisition method for DS-UWB signals are investigated and then the channel impulse response has been studied via simulation.Synchronization and the signal acquisition have also been performed for DS-PAM transmitter and IEEE 802.15.3a Channel model which are simulated using Matlab code.The method use pilot signal and correlator estimate the initial position of the desired signal,and use ML criterion realize synchronization estimation and signal acquisition.The simulation results are presented and discussed.We analyze the relativity of the receive signal with a set pilot signal which though two main kinds of UWB channels (AWGN,IEEE.802.3a) using different Eb/N0.The theoretical analysis including a simulation study indicates the effectiveness of pilot signal method to perform the UWB synchronization estimation and signal acquisition.By analyzing simulation results,this method is proven in a simple and high precision,and it also reduces the complexity of UWB transmitter and system process time.
