Digital radio outage due to selective fading - Observation vs prediction from laboratory simulation
Abstract
A statistical model (introduced in a companion paper) of fading on a radio path is used with laboratory measurements on a digital radio system to estimate the outage due to multipath fading, where outage is the time that the bit error rate (BER) exceeds a threshold. Over the range of BER of interest (10 to the -6th to 10 to the -3rd), the calculated outage agrees favorably with the outage observed during the period for which the fading model was developed. It is further shown that the calculated outage, when scaled to a heavy fading month on the basis of single-frequency, time-faded statistics, agrees equally well with the outage observed on the same path during a heavy fading month.
