TETRA (Terrestrial Trunked Radio) physical layer PI/4-DQPSK modulation
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 ETSI EN 300 392-2 V3.4.1. 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 model includes PI/4-DQPSK modulation. The specification also includes other modulation schemes.
