| Abstract: | Aiming at the problem that the aeronautical channel is complex and the signal is affected by multi-path effects during the transmission, a channel estimation method based on LS algorithm using the pilots in L-DACS1 frame is designed. And this method, which is applied in a practical project, is implemented in hardware using DSP chip TMS320C6713.The result shows that this method of channel estimation can meet the reliability requirements of L?DACS1 system during high speed transmission. |
