A Novel OFDM Spreading System with Spatial Domain Processing and MMSE-MUD

摘要：

In this paper, we propose a novel scheme that joints two-level spreading OFDM and beamforming. For further interference suppression, we assign a proper spreading code at transmitter and employ the Minimum Mean Square Error-Multiuser Detection (MMSE-MUD) equalizer at receiver. Simulation results show that the proposed system outperforms the conventional twolevel spreading OFDM system under multipath fading and narrow band jamming channels.
