Abstract

Dual hop wireless links offer a simple means of achieving broad coverage through low power transmitters. But, such systems are not immune from fading present in all wireless systems. While several fading models exist, fading treated as a cascading process, namely the cascaded model, allows flexibility in describing channel conditions that are far worse than those existing in Nakagami channels. In this work, an exact analysis of a dual hop link operating in a cascaded N*Nakagami channel is studied. The error rates were estimated using the exact model and compared to the results obtained using random number simulation. These results show an excellent match suggesting the strength of the approach. While the dual hop systems might offer simplicity, the error rate analysis in such systems illustrates that the performance is worse than what is seen in a conventional direct link.
