Table 6 Confusion Matrix at SNR =−4 dB.
From: Automatic Modulation Recognition Using Wavelet Transform and Neural Networks in Wireless Systems
ASK2 | ASK4 | ASK8 | |
|---|---|---|---|
ASK2 | 99.4 | 0.4 | 0.2 |
ASK4 | 0.1 | 99.1 | 0.8 |
ASK8 | 0.1 | 0.6 | 99.3 |
- The confusion matrix shows a high percentage of correct ASK intra-class recognition when SNR is not lower than
dB.
