Abstract: Abstract:By exploiting path diversity, conventional RAKE receiver use cross-correlation operation on multipath induced signal and combining weight at each finger to improve signal-to-noise ratio, thus reducing bit error rate. Based on the same structure, generalized RAKE (G-RAKE) receiver proposed by Wang and Bottemley can suppress both own-cell and other cell interference, multiuser interference (MUI), intersymbol interference (ISI) and noise to yield even lower bit error rate. However, G-RAKE receiver which requires different orthogonal spreading codes for varing symbols makes it’s use impractical. In this thesis, we propose a modified version of G-RAKE receiver for the case of multiple base stations, which allows each user to use its user-specific orthogonal spreading code (independent of symbols) in more practical situations. We also provide theoretical analysis and computer simulations to verify the effectiveness of the proposed receiver.
