| Summary: | 碩士 === 大葉大學 === 電信工程學系碩士班 === 95 === The evaluation of system performance of an MC-DS-CDMA (multicarrier direct-sequence coded-division multiple-access) system with dual-dimension (antenna diversity) Rake receiver is proposed in this investigation. The working environment for the scenario is considered as situating in frequency selective fading. Furthermore, some of the system parameters, e.g., the resolvable multipath number, the number of a Rake receiver, the fading parameter the power decay factor MIP (multipath intensity profile), and the correlation characteristic between the antennas, are adopted for analyzing. It is the original proposal of such scenario with dual-dimension Rake receiver for the MC-DS-CDMA system. In order to validate the accuracy of the derivative, a lot of numerical results are conduct in this paper. It is worthwhile claiming that is not only the fading parameter of the correlated-fading model dominates the system performance of the MC-DS-CDMA system, but the number of antennas also definitely affects the system performance.
