Abstract
Multi-antenna space-time pre-coding at the transmitter as a modern signal processing technology can use im -perfect channel state information or partial channel state information to improve the system capacity or reduce bit error rate , thus becoming the research hot in wireless mobile communication .According to the transmitter using the channel state infor-mation case ,pre-coding techniques can be divided into imperfect channel pre-coding techniques and partial channel pre-coding techniques .In this paper ,the Space-Time Pre-coding for multi-user MIMO multi-carrier systems are studied ,multi-user MI-MO precoding based on codebook is focused on ,a limited feedback precoding method for multi-user MIMO-OFDM based on codebook perturbation is proposed .关键词
