METHOD AND APPARATUS FOR DS-CDMA INTERFERENCE SUPPRESSION USING CODE-SPECIFIC COMBINING

摘要

Interference, such as inter-symbol interference, from a symbol of interest in a RAKE receiver (200) is reduced. The RAKE receiver comprises a plurality of RAKE fingers (220), a processor (230), and a combiner (232). The plurality of RAKE fingers despread symbols received over multiple paths of a multi-path channel. The processor determines cross-correlations between symbol waveforms from different symbols and multiple paths. The combiner combines the despread symbols using the cross-correlations to reduce interference from the symbol of interest. ® KIPO & WIPO 2007
