| Abstract(in English) | A frequency-domain block signal detection using maximum likelihood detection (MLD) employing QR decomposition and M-algorithm (QRM-MLD) can bring the BER performance of the cyclic prefix inserted single-carrier (CP-SC) transmission close to the matched filter (MF) bound. Recently, we showed that the training sequence-aided SC (TA-SC) transmission using QRM-MLD frequency-domain block signal detection can achieve the BER performance close to the MF bound while reducing the number of surviving symbol-candidates. To further improve the BER performance, transmit diversity technique is effective. In this paper, we present the BER performance of CP-SC and TA-SC transmission using QRM-MLD frequency-domain block signal detection and cyclic delay transmit diversity (CDTD). We show that if the number of surviving symbol-candidates is small, the CP-SC transmission limits the performance improvement since the probability of removing the correct symbol-candidates at early stages increases due to the increased number of equivalent propagation paths. On the other hand, we show that even if the number of surviving symbol-candidates is small, the TA-SC transmission can achieve the BER performance close to the MF bound irrespective of the number of transmit antennas. |
