Table 2 Proposed features
From: Robustness of digitally modulated signal features against variation in HF noise model
Feature | p | x | Suggested use |
|---|---|---|---|
d1 = std(d max (x, p)) | 8PSK | 2PSK 4PSK 8PSK 16QAM 32QAM 64QAM | Discrimination between MPSK and MQAM |
d2 = meand max (x, p)) | 2PSK | 2PSK 4PSK 8PSK | Discrimination between 2PSK and (4PSK, 8PSK) |
d3 = mean(d max (x, p)) | 4PSK | 4PSK 8PSK | Discrimination between 4PSK and 8PSK |
d4 = mean(d max (x, p)) | 16QAM | 16QAM 32QAM 64QAM | Discrimination between 16QAM and (32QAM, 64QAM) |
d5 = std(d max (x, p)) | 64QAM | 32QAM 64QAM | Discrimination between 64QAM and 32MQAM |
