MIMO,multicatrier and linkadaptive Inodulation techniques are a few key kinds of physical layer techniqucs infuture wireless communication mission system.MIMO technique have a excellent performance in promoting spectral efficiencies,multicatrier and CDMA tcchniquc can alleviate the frcqucncy-sclective fading effect effectively.Combinating MIMO technique and MC-CDMA scheme into MIMO MC-CDMA system will improve the performance and capacity of a mobile communications system.Introducing the adaptive modulation technique into MIMO MC-CDMA system can take full advantage of wireless channcl capacity,and improve data rates more effectively.At last achieved the final structure of the digital base-band transceiver for a airspace multiplexing MI MOMC-CDMAsystem.This Paper use a hardware's emulation model for MIMO channel to achieve the Joint debugging and functional verification,and compared with the software simulation results obtained a good Performance.
