Abstract :
We have suggested a novel time-dispersion multipath channel model for wideband wireless systems. This extended model incorporates the microcell site-specific information by including the frequency dependence of individual paths. A new super-resolution algorithm has been used to estimate the path delay and frequency dependence of each individual path. The focus is on the microcellular environment with DS-CDMA and spatial filtering in mind
