In this paper, UWB-IR sensors are considered in wireless sensor networks (WSNs) with two different IEEE 802.15.4a based signalling; (i) binary pulse position modulation (BPPM) and (ii) combined BPPM/binary phase shift keying (BPPM/BPSK) modulation, for the detection of primary users. In addition to the modulation effects, the effects of each sensor's false alarm and misdetection performances and the effect of signal-to-noise ratio (SNR) of the sensor-fusion center link have been investigated. For practical implementation of the WSN, some suggestions have been provided. © 2013 IEEE.trinfo:eu-repo/semantics/closedAccessPrimary user detectionUltra wideband (UWB) systemsWireless sensor networks (WSNs)Binary pulse position modulationIEEE 802.15.4aModulation effectsPrimary user detectionsSignaltonoise ratio (SNR)Ultra wideband impulse radioUltrawideband systemsWireless sensor network (WSNs)Broadband networksModulationPulse position modulationSensorsUltra-wideband (UWB)Wireless sensor networksConference Object10.1109/SIU.2013.65311932-s2.0-84880904639N/AN/A
