Abstract
Computer implemented methods and systems for the prediction of the reception of a desired in-band on-channel digital audio broadcast signal (IBOC DAB) are described. A method includes computing a first ratio of a weaker undesired adjacent broadcast signal to a stronger undesired adjacent broadcast signal; computing a second ratio of the desired IBOC DAB signal to the stronger undesired adjacent roadcast signal. The method also includes computing a minimum allowable reception ratio based on the second ratio and the slope and intercept of a line, wherein the slope and intercept of the line is based on both (i) a plurality of ratios of a weaker adjacent broadcast signal to a stronger adjacent broadcast signal and (ii) a plurality of ratios of a desired IBOC DAB signal to a stronger adjacent broadcast signal. Reception is predicted when the computed minimum allowable reception ratio is less than the first ratio.
