Table 1 Comparison of receivers complexity
From: Interference-aware receiver structure for multi-user MIMO and LTE
Receiver | Real multiplications | Real additions |
|---|---|---|
Interference-aware receiver (equal energy alphabets) |
| 8n r + 10M + log(M) - 4 |
Interference-aware receiver (non equal energy alphabets) |
| 12n r + 18M + log(M) - 6 |
Max-log MAP receiver | 2M2n r + 8Mn r | 6M2n r + 4Mn r + log(M) - M2 |
Single-user receiver (equal energy alphabets) | 10n r + 6 | 10n r - 3 |
Single-user receiver (non equal energy alphabets) |
| 10n r + 3M + log(M) - 3 |
