| Abstract(in English) | A frequency-domain block signal detection using maximum likelihood detection (MLD) employing QR decomposition and M-algorithm (QRM-MLD) can significantly improve the bit error rate (BER) performance of the cyclic-prefix inserted single-carrier (CP-SC) block transmissions in a frequency-selective fading channel, compared to the frequency-domain equalization (FDE) based on the minimum mean square error criterion (MMSE). However, if the number of surviving symbol candidates is small, the performance improvement is limited since the probability of removing the correct symbol candidates at early stages increases. In this paper, to solve this problem, we apply an MMSE QRM-MLD frequency-domain block signal detection to the CP-SC transmission and show by computer simulation that the MMSE QRM-MLD can improve the BER performance while reducing the number of surviving symbol candidates compared to the conventional QRM-MLD. We also compare the achievable BER performance and computational complexity of CP-SC transmission using MMSE QRM-MLD frequency-domain block signal detection to that of the training sequence-aided SC (TA-SC) transmission using QRM-MLD frequency-domain block signal detection. |
