Abstract :
Spread spectrum-based code division multiple access (CDMA) has become very important to cellular and personal communications, due to its characteristics such as potential capacity, antimultipath capabilities, soft capacity, and soft hand-off. 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
