Table 2 Computational complexity comparison
From: A novel physical layer scheme based on superposition codes
Number of operations per each iteration | Proposed decoder | AMP, Rush et al. [14] |
|---|---|---|
Sum | 2M L(n−1)+n | 2M L(n+1)−n−L |
Multiplication | n(2M L+1) | n(2M L+1)+3M L |
Division | – | 2M L+n+1 |
Exponential | – | ML |
