An Improved Algorithm of Packet Acquisition for UWB Wireless Sensor Network

Abstract

Wireless Sensor Networks (WSNs) in combination with ultra-wideband (UWB) technology can be widely employed in the industrial field. For instance, to monitor different parameters among harsh environments in hard-to-reach places. Hence, one of the requirements for transmitters of this network is low cost In our paper, considering simple nodes implementation, we present the novel physical layer algorithm for packet acquisition at the receiving side. The acquisition in our approach is performed using data symbols, so the preamble overhead is eliminated. Also, the scheme performance does not degrade. A UWB WSN is modeled in MATLAB. The obtained dependence of an effective data transfer rate on a signal to noise ratio (SNR) demonstrates the efficiency of the new method compared with the existing acquisition approach.
