Improved estimation of the K-factor for Rician channels emulation in a reverberation chamber

In many radio propagation environments, the timevarying envelope of the received signal can be statistically described by a Rician distribution. Recently, reverberation chambers have been proposed to simulate Rician radio environments with controllable K-factor. However, evaluation of Rician K-factor out of RC measurements must be analyzed very carefully. The paper provides an analytical formulation of both the estimation of K and the confidence interval associated with its estimation.
