In this paper we introduce a wideband three-element diversity antenna for compact wireless communication systems operating at the 4-6 GHz band. A series of experiments to characterize the diversity performance of the antenna for non-line-of-sight (NLOS) indoor multipath environments have been conducted. From these experiments, we calculate envelope correlation, power imbalance, and diversity ga...
In this paper we study the concept of Arveson spectrum on locally compact hypergroups and for an important class of compact countable hypergroups . In thiis paper we study the concept of Arveson spectrum on locally compact hypergroups and develop its basic properties for an important class of compact countable hypergroups .
'I A cavity pressure method for measuring t he gain of hearing aids has been--developed. It has the advantage of req uiring no " dead " room, allo~ing a compact setup. The method has been investigated as to its validity and t he degree to which diffraction effects are avoided. Comparisons with free-field data are made. The applicability of results obtained by this method to t he specifi cation ...
