Statistical analysis of measurement uncertainty in total radiated power of wireless devices in reverberation chamber

摘要

Due to the explosive increase of wireless devices, efficient over-the-air testing of such devices is highly desirable. The reverberation chamber (RC) offers efficient and cost-effective means to determine performance metrics of wireless devices, such as total radiated power (TRP). In this study, the distribution of the measured TRP in an RC is analytically derived, based on which the statistics (i.e. mean, variance) of the measured TRP are derived as well. RC measurements have been performed to verify the analytically derived statistics.
