Abstract -- In this paper,1
a new distribution, named POCA, is introduced for
modeling envelope fluctuations due to fast fading in indoor environments. The main
motivation has been the small number of scatterers in those environments, which makes
the central limit theorem invalid for in-phase and quadrature components. Hence they are
no longer Gaussian and envelope is not Rayleigh-distributed. POCA, the new envelope
distribution,1
is obtained by assuming t distribution for in-phase and quadrature
components. In this comment, first a short summary of three possible approaches for
deriving the envelope distribution for indoor channels, where the number of scatterers is
usually small, has been provided. Thereafter, based on various detailed theoretical
