Abstract:
1. A computer implemented method of predicting the reception of a desired in-band on-channel digital audio broadcast signal, the method comprising: (a) computing a first ratio of the field strength of a weaker undesired adjacent broadcast signal to the field strength of a stronger undesired adjacent broadcast signal; (b) computing a second ratio of the field strength of the desired in-band on-channel digital audio broadcast signal to the field strength of the stronger undesired adjacent broadcast signal; (c) 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 in-band on-channel digital audio broadcast signals to a stronger adjacent broadcast signal; (d) predicting reception of the in-band on-channel digital audio broadcast signal when the computed minimum allowable reception ratio is less than the first ratio.
