Abstract(in English) | Block-Spread CDMA (BS/CDMA) communication system has received much attention as an MUI-free system even under the multi-path environments, and it might be expected to improve further BER characteristics by introducing receiving antenna arrays. But, in this system there occurs inter-symbol interference in each data-block, and if we use an MMSE detector to suppress it, it causes considerable processing cost. In this paper, using the property that the correlation matrix in the DFT domain for the system constitutes a block diagonal matrix, a low complexity reduced-rank MMSE detector is proposed. Computer simulations for the proposed detector are conducted, and the effectiveness of the method is shown in terms of SINR and BER characteristics. |
