Development and Evaluation of a Prototype Multichannel APD Measuring Receiver
2007 IEEE International Symposium on Electromagnetic Compatibility, 2007Co-Authors: K Gotoh, Shigehisa Ishigami, Toyofumi Shinozuka, Y. Matsumoto, M. UchinoAbstract:Development of a multichannel APD Measuring Receiver is necessary to enable evaluation of the impact of wideband disturbance emissions on digital wireless communication services which use multicarrier transmission systems. We describe technical details of the world's first multichannel APD Measuring Receiver which we have developed using a general-purpose ADC-FPGA board. Our measurements of the basic performance of this Receiver show that the Receiver is suitable for practical use. We also used the developed Receiver to measure the APDs of disturbance emitted from a microwave oven at five frequency points (1 MHz apart). These results indicate the significance of the multichannel APD Measuring Receiver.

Three Fast Ways of Measuring Receiver Sensitivity in a Reverberation Chamber
2008 International Workshop on Antenna Technology: Small Antennas and Novel Metamaterials, 2008Co-Authors: Mats Andersson, Charlie Orlenius, Per-simon KildalAbstract:The traditional way of evaluating Receiver sensitivity is to measure the Total Isotropic Sensitivity (TIS) in an anechoic environment. Very few wireless terminals with small antennas are used in an anechoic environment. This paper will describe three alternative methods to measure the Receiver sensitivity in a reverberation chamber, each of which can be done in less than 10 minutes which is much faster than measurements in anechoic chamber. The fastest method is the average fading sensitivity AFS that in contrast to TIS also be used to measure Receiver sensitivity of multi antenna terminals for antenna systems with diversity and MIMO capability. The paper includes the first published TIS and AFS results for WCDMA terminals obtained in a reverberation chamber. The agreement to TIS measurements in anechoic chambers is shown to be good.
