Adaptive diversity combining for wide band code division multiple access (W-CDMA) based on iterative channel estimation

摘要

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 I_known and I_unknown components, precomputing said I_known interference components, iteratively estimating channel interference after removing I_known 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 selecting the combining technique (MRC or EGC) automatically depending on the channel condition. The instant invention also provides a system and configured computer program product for carrying out the above method.
