Generalized Exponential Decay Model for Power–Delay Profiles of Multipath Channels (original) (raw)

This research develops a generalized model for power-delay profiles (PDPs) of multipath radio channels, accounting for the components of line-of-sight paths, specular reflections, and diffuse reflections through single and multiple scattering. The model is presented as a composite of exponentially-decaying clusters that captures the various multipath components, facilitating the analysis of key metrics such as channel gain and delay spread. This PDP model provides insights for characterizing propagation environments and evaluating the performance of OFDM transmission systems.
