系统内冗余或重复数据的度量,表明存储和潜在性能问题效率低下。
1 SR = 1 LDPC
1 LDPC = 1 SR
例子:
将15 信号冗余转换为LDPC代码冗余:
15 SR = 15 LDPC
| 信号冗余 | LDPC代码冗余 |
|---|---|
| 0.01 SR | 0.01 LDPC |
| 0.1 SR | 0.1 LDPC |
| 1 SR | 1 LDPC |
| 2 SR | 2 LDPC |
| 3 SR | 3 LDPC |
| 5 SR | 5 LDPC |
| 10 SR | 10 LDPC |
| 20 SR | 20 LDPC |
| 30 SR | 30 LDPC |
| 40 SR | 40 LDPC |
| 50 SR | 50 LDPC |
| 60 SR | 60 LDPC |
| 70 SR | 70 LDPC |
| 80 SR | 80 LDPC |
| 90 SR | 90 LDPC |
| 100 SR | 100 LDPC |
| 250 SR | 250 LDPC |
| 500 SR | 500 LDPC |
| 750 SR | 750 LDPC |
| 1000 SR | 1,000 LDPC |
| 10000 SR | 10,000 LDPC |
| 100000 SR | 100,000 LDPC |
