TETRA is the digital version of the "Walky Talky" used by departmets like police, fire-fighters or ambulance in some countries.

This simulink model implements parts of the physical layer as described in the specification. It includes:

- convolutional encoding
- scrambling
- timeslot generation
- modulation / demodulation
- bit error rate comparison

It is not though NOT complete! Be aware of the fact that convolutional encoding is a different one than in the specification and block encoding and interleaving are missing.

This is the 4-QAM modulation model. There is also a model applying the PI/4-DQPSK modulation
