摘要：
On the basis of a scenario that assumes the existence of a BC (branch correlation) in the environments of an MC-DS-CDMA (multi-carrier direct-sequence coded-division multiple-access) system, a two-dimensional Rake (2-D Rake) receiver for such a system is proposed and designed in this research. The performance of the proposed system is validated by an evaluation that considers the state of the working space in frequency-selective fading environments. Furthermore, some of the system parameters, e.g., the resolvable multipath number, the finger number of a Rake receiver, the fading parameters, the power decay factor, the MIP (multipath intensity profile), and the correlation characteristics between the antennas, are adopted for analysis, thus constituting the original proposal for a scenario with this kind of receiver in this system. To validate the accuracy of the derivation, some of the numerical results are presented in this report. It is worthwhile to assert that the fading parameter of the correlated-fading model dominates the performance of the MC-DS-CDMA system and that the number of antennas also definitely affects the system performance.
