Abstract(in English) | In order to realize a communication by the minimum transmission power of mobile stations on indoor environments as medical facilities, it's important to reduce the transmission point that cannot receive at a base station. As solutions of this problem, we consider the diversity technique, as space diversity and polarization diversity, is effective. The polarization diversity reception technique that makes branch each 3-axis components of electric field and magnetic field is applied. We also propose the 6 branch delay combiner system which is composed one receiver and apply RAKE diversity scheme as a reception system. To clarify the effect of our proposal, we manufactured the prototype system for trial and evaluated the characteristics. We confirmed that each antenna effectively works as a diversity branch at a same point and that the combination of the delay combiner system and 3-axis EH antenna improves the deterioration of the SN rate on indoor environments. |
