Abstract: The present invention provides a method for adaptive diversity combining for Wide Band Code Division Multiple Access (W-CDMA) comprising: splitting multi-path interference into Iknown and Iunknown components, precomputing said Iknown interference components, iteratively estimating channel interference after removing Iknown components of the multi-path interference from the pilot symbols, using the convergence/divergence of the iteration as an indicator of the channel condition, and The instant invention also provides a system and configured computer program product for carrying out the above method.
