| 3 | 1 | ABDALLAH, Hussein | As we know that the Down link of voyage 1 use the RS(Reed–Solomon) coding when it navigated near the Uranus and Neptune. We change the coding module with RS coding. |
| 4 | 1 | ABDALLAH, Hussein | We simulate the BER with 4 RScoding: |
| 5 | 1 | ABDALLAH, Hussein | |
| 6 | 2 | ABDALLAH, Hussein | * RS (15,11,2) coding rate = 0.73 |
| 7 | 2 | ABDALLAH, Hussein | * RS (255,233,11) coding rate = 0.913 |
| 8 | 2 | ABDALLAH, Hussein | * RS (255,239,8) coding rate = 0.937 |
| 9 | 2 | ABDALLAH, Hussein | * RS (204,188,8) coding rate = 0.92 (shorten from ) RS(255,239,8) |

| 14 | 4 | ABDALLAH, Hussein | And we get the simulate BER data with RS coding as shown in the table below: |

| 18 | 6 | ABDALLAH, Hussein | We draw then all BER curves in one figure as following: |
