| Abstract(in English) | There has been growing demand for high data rate in wireless communication. One promising solution is to use the orthogonal frequency division multiplexing (OFDM) system with space division multiplexing (SDM) for increasing the transmission rate. Since the SDM/OFDM systems transmit the different data using the same frequency, so it is necessary to reduce the co-channel interference for separating the simultaneously received signals. Previous studies have shown that the maximum likelihood detection (MLD) has the best BER performance. However, if the received powers of the desired symbols from different antennas are nearly the same, MLD shows poor detection property. Since almost the same replicas may generate, even if the combination of the transmitted symbols are different. To reduce this problem, in this paper, we propose the antenna-phase pre-controlled SDM/OFDM with polarization diversity. The proposed system uses an imbalance effect of polarization and pre-phase control scheme to reduce the same power and phase generation for increasing MLD detection property. From the simulated results, the proposed system shows better BER performance than that of the conventional SDM/OFDM. |
