Abstract
Estimation method of radiated power from radio transmitter is proposed by using the statistical parameter measured with reverberation chamber system. It is considered that the multipass wave mixed by stirrer inside the reverberation chamber is a kind of random noise. We show theoretically that the cdf value of 63.2% of an envelope of direct wave with multipass wave is not depend on the rate of direct wave and mulltipas wave. And also we show the experimental result for estimation of radiated power from radio transmitter by using reverberation chamber system.
