Table 2 SNR for modulation scheme in WiMAX[18, 19]
From: SNR-aware and power-efficient multicast cooperative routing algorithm in wireless networks
Modulation | Code rate | Achievable data rate (20 MHz) | SNR (in dB) |
|---|---|---|---|
QPSK | 1/2 CTC | 20 Mbps | 8 < SNR ≤ 9.4 |
QPSK | 3/4 CTC | 30 Mbps | 9.4 < SNR ≤ 11.2 |
16 QAM | 1/2 CTC | 40 Mbps | 11.2 < SNR ≤ 16.4 |
16 QAM | 3/4 CTC | 60 Mbps | 16.4 < SNR ≤ 18.2 |
64 QAM | 1/2 CTC | 60 Mbps | 18.2 < SNR ≤ 22.7 |
64 QAM | 3/4 CTC | 90 Mbps | 22.7 < SNR |
