| Abstract: | Aiming at the more requirements of unmanned aircraft vehicle （UAV） information transmission rate and reliability, research on simulation of MIMO-OFDM in UAV data link. Based on analysis of technology features of MIMO and OFDM, put forwards MIMO-OFDM technology UAV data link model, use Matlab to simulate MIMO and SISO UAV data link bit error rate performances adopt OFDM technology, then give the further research content. The simulation results show that, use MIMO-OFDM technology can effectively reduces bit error rate, overcomes inter symbol interference, and is better suited to the UAV data link than the traditional SISO system and single carrier transmission technique. |
