High capacity radio link performances are principally affected by the presence of multipath propagation, so that the link can be out of service even when a high signal to noise ratio is present in the system. Hence, in order to fulfil the required quality several countermeasures for multipath fading have been proposed. In this paper we develop a theoretical analysis of the amplitude IF equalizer performances for a 16QAM 140 Mb/s digital radio system in presence of multipath dispersive fading. In...
High capacity radio link performances are principally affected by the presence of multipath propagation, so that the link can be out of service even when a high signal to noise ratio is present in the system. Hence, in order to fulfil the required quality several countermeasures for multipath fading have been proposed. In this paper we develop a theoretical analysis of the amplitude IF equalizer performances for a 16QAM 140 Mb/s digital radio system in presence of multipath dispersive fading. In particular, we obtain results for both non-minimum and minimum phase fading and we compare, by using the 'signature' concept, the obtained results with the system performances when the receiver is without any protection.
