Recently, it has been shown that a parasitic element can be used to fully decouple closely spaced antennas. However, the decoupled antennas suffer from narrow bandwidth, as compared to the bandwidth of isolated single antennas, which is also the case for other decoupling methods, such as multiport conjugate match and neutralization line. In this paper, we investigate the potential in bandwidth enh
In this paper, we consider optimal and suboptimal linear receivers for a given user in a frequency-selective multiuser environment. The optimal linear receiver combining all the samples from the frames and the multipath components, according to the MMSE criterion, is designed. Due to the complexity of this receiver, two suboptimal receivers are considered: (i) an optimal frame combining receiver,

Abstract in Undetermined Over the last few years the interest in distributed generationand island operation of small production units hasincreased. Many of the existing such units are hydro power stations with induction generators. These are not initiallyconstructed for island operation, but with some extraequipment this kind of operation is feasible. In this paper the behaviour of two parallel-op

Many activated sludge wastewater treatment control strategies have been proposed in the literature; however, the literature does not provide a clear basis for comparison of these strategies because of the many confounding influences that have an impact on the system. Complicating the evaluation is the lack of standard evaluation criteria. Simulations provide a cost-effective means for the evaluati
