In this paper, the ELF atmospheric noise measured by a low-temperature superconducting receiver is analyzed and modeled. The measured data are firstly reconstructed by wavelet transform to remove baseline wandering. And then the harmonics radiated by power line are estimated and subtracted by least square estimation. After preprocessing the measured data, Hall model and symmetric a stable (SaS) distribution...
Network simulator (NS) is a kind of enwlation software with powerful functions. Its biggest function is that it can check and compare the performances of various kinds of protocols and provide experimental data for researchers to analyse whether their performances are good or bad. This paper proposes a method to design network topology and script program, then uses NS to compare performances of network...
