Outage prediction of digital radio systems

It is well established that the performance of digital radio systems is often limited by the amplitude and group delay distortions which accompany frequency selective fading, and the concept of the `system signature¿ has been developed for predicting the outage probability of such systems. The letter presents a new outage prediction technique and introduces the concept of a `normalised system signature¿ which enables comparisons of modulation schemes and equaliser implementations.
