| Abstract: | In recent years,signal modulation recognition becomes a research hotspot in the area of civil radio monitoring,cognitive radio and electronic countermeasure.Some common satellite communication signal modulation types are analyzed,such as BPSK,QPSK,8PSK,16QAM,32QAM and 16APSK.And the recognition technique of each modulation type is studied.At last,a recognition method is put forward which is easy to realize and has a high recognition rate.Both the theoretical analysis and simulation confirm the effectiveness of the algorithm. |
| Keywords: | modulation type modulation recognition satellite communication |
