Table 1 Signaling overhead and numerical complexity
From: Cooperative DoA-only localization of primary users in cognitive radio networks
| Distributed sensors | Fusion center | |
|---|---|---|
| Signaling overhead | - | O(M) |
| Signaling overhead (virtual array case) | O(N(m−1)) | O(M) |
| Numerical complexity | O(m3) | O(max{m,M}3) |
