Abstract
In this paper, we propose a novel scheme that joints two-level spreading OFDM and beam forming. 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 two-level spreading OFDM system under multipath fading and narrow band jamming channels.
