Abstract: An adaptive transmission scheme of the channel environment in the multi-antenna wireless transmission system can raise the spectrum use rate and power efficiency of the communication system. Compared with traditional single antenna input and single antenna output, the channel environment in MIMO wireless communication system is more complex. When the terminal is moving, the different types of channels between terminal and base station can be gone through and then its capacity can be changed more largely. Embodiments of the disclosure are directed to systems that transmit high speed data by way of a plurality of transmitting and/or receiving antennae, and particularly to a transmission scheme in different channel environments in a multi-antenna wireless transmission system.
