Abstract :
A method to compute outage time during clear air conditions on any radio path for various types of digital modulation is proposed. The performance of digital systems depends on combined effects of in-band amplitude dispersion (IBAD) in the channel bandwidth, and of carrier to noise ratio (CNR). Outage time is then computed for a given period using the statistical dependence of IBAD and CNR in the propagation mechanisms occurring on the path and using the formal relation of IBAD with CNR characterising the digital equipment in service.
