| Abstract(in English) | Multi-user multi-input multi-output (MIMO) is known as a spectrum efficient multiplexing technique. When multi-user MIMO is applied to cellular systems, MIMO signal detection scheme which can provide good bit error rate (BER) performance in the presence of strong co-channel interference is required. Recently, we applied a maximum likelihood block detection using QR decomposition and M algorithm (QRM-MLBD) to the uplink single-carrier (SC) multi-user MIMO in a cellular system and showed that QRM-MLBD can significantly improve the uplink capacity compared to the frequency-domain minimum mean square error detection (MMSED). However, QRM-MLBD requires quite high computational complexity. In this paper, we introduce the iterative frequency domain interference cancellation (FDI^2C) instead of QRM-MLBD and investigate its achievable uplink capacity. Its is shown that iterative FDI^2C can achieve the same uplink capacity as QRM-MLBD with much reduced complexity. |
