A novel approach with superresolution and path frequency dependence for channel modeling and application in CDMA cellular system

We study the multipath propagation effects of cellular communication channels. In particular, the frequency dependency of multipath arrivals is characterized using a novel superresolution technique, named the SVD eigen-matrix pencil method, to provide physical insight of the path “history”. The conventional broadband model is extended to include the frequency dependence of individual rays which can be used to classify the ray arrivals and to provide physical insight of the channel. This approach may be crucial to the analysis and design of broadband CDMA systems
