| Abstract(in English) | Recently, the wireless communication technology is required to carry a large amount of digital infer- mation with spread of the mobile phone and wireless LAN. Space Division Multiplex (SDM)system has actively studied for increasing the channel capacity. However, SDM requires a signal identifying technique at the receiver in order to identify each transmission stream. Although Maximum Likelihood Detection (MLD)shows the best BER performance, it requires prohibitively large amount of computation to implement at the receiver. To mitigate the above mentioned problems, we have proposed the sequential decision algorithm for QRM-MLD in order to reduce the computation without performance deterioration. However, the number of computation of the proposed system is l by 10 as much as conventional MLD and still remained the BER degradation. Thus, for improving the performance of the proposed system, we propose the branch cutting method with channel ranking. Prom the simulation results, the number of the proposed method computation is aproximately an half as much ELS the conventional sequential decision algorithm. |
