Measurement of spectral efficiency.
| | Feedback overhead | | | |
| | BF scheme | SCSL() | SCIS() | SCSL() | SCIS() | SCSL() | SCIS() |
| | System SE (bit/s/Hz) | 7.153 | 8.865 | 7.974 | 8.865 | 8.592 | 9.632 |
| | System SE gain (compared to SC) | ā9.73% | 11.88% | 0.63% | 19.40% | 8.43% | 21.55% |
