Table 2 Comparison on computational complexity among TFC identification methods
From: A power-efficient synchronization scheme for the MB-OFDM-based UWB systems
Operation | Proposed | Scheme in [ 9 ] | CC algorithm |
|---|---|---|---|
Complex multiplication | 0 | 4N s D a | 4 × 128N s D a |
Real addition | (3 + 14.4)N s D a | 8N s D a | 4 × 127N s D a |
Real comparison | (1.04 + 10.2)N s D a | 4N s D a | 4 × N s D a |
ABS | N s D a | 4N s D a | 4 × 128N s D a |
