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
Pharmacists must ensure that patients know how to make the best use of their medication. An education programme was initiated in the southernmost part of Sweden during 1990 in order to improve the communication skills of pharmacy staff and the information given to customers. Customers with prescriptions for Turbuhaler were asked to 'show-and-tell' how they used their inhalers, and the results were
