This paper discusses ultra wideband (UWB) system bit error rate (BER) performance in additive white Gaussian noise (AWGN) channel in the presence of partial band interference. In most of the cases in UWB context, even narrowband interference approaches are reasonable. The study has focused on direct sequence (DS) based UWB system that utilizes binary pulse amplitude modulation (BPAM) as a data ...

Zigbee is one of the major sources of interference in 2.4GHz band for WLANs. It is seen whenever any Zigbee system is operating near to the WLAN system and transmitting signal at same frequency, time as of WLAN’s, the later ones performance detoriate severely. So in this paper an algorithm is proposed to estimate Zigbee interference component present in all OFDM based WLANs sub-carriers and can...

As a main interference to track circuit signal, the interference of the traction current(ITC) will directly influence the transmission quality of track circuit signal and even lead to signal distortion which would endanger the traffic safety. The ITC has a complicated formation mechanism and it is affected by factors of train compositions, load and running speed, so it is hardly possible to est...
