Table 1 Proposed power allocation strategies
From: Outage minimization for parallel fading channels with limited feedback
| Number of channels | M < 10 | M ≥ 10 |
| Optimal approach | SPSA | - |
| Approximation | POHPA | - |
| High Pav | PFPPC (L ≥ 16, | GA (L ≥ 16, |
| PFPPC+ZPiOR or PFPPC+EPPR) | GA+ZPiOR or GA+EPPR) |
