Technische Daten

• Perform call set-up and loopback between two GSM mobiles
  – Optionally, voice can be decoded and output locally (or to network)
• Implements ETSI GSM recommandations
  – Most voice-call related layer 1 and 2 messages and primitives
  – Subset of layer 3 Call Control messages
• Allows BTS emulation and basic call establishment
• Targeted at Lyrtech SFF SDR DP
  – Based on TI DM6446 SOC DSP (ARM9 + C64x DSP) and Virtex 4 FPGA
  – Retargetable C-Code for protocol layers
• Code is non-OS specific
• Code runs on DSP or can easlily be splitted between DSP and GPP
• Uses 64xx assembly-coded Lyrtech GSM voice coding libraries
  – FPGA designed using Model-Based Design
• Allows system simulation and verification
• Can be easily retargeted at other FPGAs
  – SFF SDR platform is RF/IF/Baseband modularized, so it can be retargeted to
  customer specific technologies for IF and RF sections
• Applications:
  – Pico base stations
  – GSM monitoring systems
  – Advanced reprogrammable multimode/SDR handhelds
  – GSM-based sensors
