Energy-efficient and Rapid Master Synchronization in Physical-layer of Wireless Sensor Networks

摘要：

　　Synchronization in physical layer of wireless sensor networks is critical in restricting complexity of tag node and power consumption.In order to reduce acquisition time and cost in feedback,the phase error estimation algorithm is proposed based on the pulse master synchronization.Because of the linear relationship between the phase error and the sawtooth correlation output using the symmetric bipolar sawtooth in the tag node,the better stability and acquisition speed can be obtained.We analyze the synchronization acquisition performance based on the master node,i.e.anchor node,at the transmitter and further verified by simulation.At the same time,the acquisition performance of the two algorithms is also compared under the non-ideal channel.??
