Table 5 Bits assignment for GR parameters Ï• 11 and Ï• 21
From: Beamforming matrix quantization with variable feedback rate
Bits for ϕ11(i) | Bits for ϕ21(ii) | Condition | Probability (iii) | Ave bits for ϕ11and ϕ21((i) + (ii)) * (iii) |
|---|---|---|---|---|
3 | 3 | ψ21 = 33.75, 56.25 | (0.35496 + 0.35146) * (0.2722 + 0.47748) = 0.5296 | 3.1776 |
|  |  | ψ31 = 11.25, 33.75 |  |  |
2 | 2 | Otherwise | 1 – 0.5296 = 0.4704 | 1.8816 |
