| Abstract: |
| According to the features of meteor burst channel,using the algorithm of iterative signal processing to perform signal detection of the extremely low SNR meteor communication system is proposed on the basis of frequency domain signal processing, and the realization steps are discussed. The algorithm is also simulated in SPW and the result shows the feasibility of the algorithm. |
