A number of radio channel models based on either geometrical or statistical methods have been proposed in literature. Many such models tend to simplify the scattering environment in indoor radio medium by assuming uniform distribution of scatterers and thereby overestimate the performance of the communication system. In this paper, the authors present a clustering based radio channel model for a wideband frequency selective Single Input Single Output (SISO) indoor wireless channel. With the transmitter and the receiver located at the foci of an ellipse, the scatterers are modeled to be present in form of clusters of scatterers distributed randomly inside the ellipse.
