Figure 1: Schematic showing measurement steps involved in quantitative chemical analysis of a sample. There are three ways of classifying the process, based on the technique (classical vs instrumental), the measurement data (single-channel vs multi-channel), or on whether additional data is needed to estimate the analyte concentration (relative vs absolute). There are a very large number of tec...

This paper explains the ultra wideband (UWB) indoor radio channel measurement procedure performed at the main building at the University of Oulu, Finland. The measurement campaign included rooms with various sizes and layouts. The frequency response of the radio channel was recorded using a network analyzer in frequency sweep mode. The impulse response of the radio channel was calculated by tak...

In this paper, we consider the question whether mobile multi-user MIMO measurements can be emulated by sequentially measuring each point-to-point link with a single channel sounder. The crucial aspect of this approach is whether it is practically feasible to keep the environment sufficiently static between sequential measurement runs. We investigate this aspect in the context of an outdoor-to-i...

Abstract Indonesia needs to improve its irrigation system by implementing respectable technology. Recently, Indonesian systems have intended switch from analog digital However, it appeared that was having some issues applying technology in many areas. For instance, delivering water sources subversives requires a computer infrastructure. A manual level monitoring tool has been used canals gauge ...

Multiple-input multiple-output (MIMO) systems have attracted lots of attentions, for their potential for high gain in channel capacity. For evaluating the performance of MIMO systems in more practical situations, more accurate channel models are necessary; and channel measurement is necessary to estimate the parameters of the channel models [1] [2]. In [2], we developed a fully parallel wideban...
