In this paper, the performance of Discrete Fourier Transform (DFT) precoded Orthogonal Frequency Division Multiple Access (OFDMA) schemes with interleaved and with blockwise subcarrier allocation is investigated and compared. Transmission with one transmit antenna is compared to transmission with multiple transmit antennas using Cyclic Delay Diversity (CDD). It is shown that the investigated DF...

In this paper, we consider the minimization of a relevant energy consumption related cost function in the context of sensor networks where correlated sources are generated at various sets of source nodes and have to be transmitted to some set of sink nodes. The cost function we consider is given by the product [rate] × [link weight]. The minimization is achieved by jointly optimizing the transm...

There is an extensive literature dealing with the interaction between groundwater and surface water, this includes major reviews on baseflow, transmission losses, baseflow recession analysis, broader aspects of low flows. Although these are mature topics in hydrology, they continue to attract strong interest, hundreds papers published leading journals over past 20 years. Our comprehensive revie...

Abstract The increasing penetration of renewable energy sources in the electricity grid brings new operational challenges. This up need for effective means to provide demand response spite its distributed nature throughout grid. Aggregators can be created manage a set such resources, but deciding how allocate an aggregator’s resources is important problem. One aspects that needs more attention ...
