It is pointed out that the turbulent tokamak edge can significantly affect the transmission of a wave in the ion cyclotron range of frequencies during auxiliary heating at the resonant layer. Because of the large edge density fluctuations, it is necessary to consider an order unity expansion parameter for the general propagator theory of wave propagation. Consequently, a renormalized theory for the scattering process is developed and utilized to determine the backscattering (one dimensional) and spectral wavenumber spread (two dimensional) of incident energy.
