1 | 2 | ptrkrysik | A BTS (Base Transceiver Station) on the GSM radio interface may use frequency hopping, that |
---|---|---|---|
2 | poses additional difficulty to transmit and receive GSM signals on the mobile side. The aim of this |
||
3 | subtask is to implement frequency hopping for a GSM mobile station. |

5 | 2 | ptrkrysik | * implementing transmission of GSM bursts according to a hopping sequence (deliverables: |
6 | code + plot(/s) showing frequency of transmitted bursts) |
||
7 | * implementing reception of GSM bursts that follows frequency hopping (deliverables: code + |
||
8 | decoded messages from the signal with hopping) |
||
9 | * extending the control interface between gr-gsm and Osmocom-BB with ability to |
||
10 | send/change hopping parameters (deliverable: code) |
||
11 | * testing the mobile station with a GSM BTS supporting frequency hopping (deliverable: |
||
12 | protocol traces in Wireshark) |
