Abstract

In multipath channels, paths often arrive in clusters. An early model that exhibits clustering was proposed by Saleh and Valenzuela in 1987, and since then, several extensions have been developed. Although these models are straightforward to simulate, little analysis of them has been carried out. Here, a generalized multipath-cluster channel model is proposed that subsumes the Saleh-Valenzuela model and its extensions as special cases. The proposed model provides a unified framework for the understanding and analysis of multipath-cluster channel models. The framework is used to derive formulas for the power-delay profile, excess-delay moments, and similar channel characteristics.
