Abstract: Abstract:As mobile communication systems continue to spread, code-division multiple access (CDMA) has become the mainstream of wireless communications. Under the demand of high speed transmission and low bit error rate, the RAKE receiver for combating channel fading has been widely used in CDMA mobile devices.
Conventional RAKE receiver combines each resolved path signal in different time slots to generate a decision statistic with higher signal-to-noise ratio for improving detection capability. Based on the same structure, generalized RAKE (G-RAKE) receiver can suppress multiuser interference (MUI), intersymbol interference (ISI) and noise to yield even lower bit error rate. In this thesis, we propose a modified version of G-RAKE receiver which allows each user to use its user-specific orthogonal spreading code (independent of symbols) in more practical situations. We also provide statistical analysis and computer simulations to verify the effectiveness of the proposed method.
