ISAC-Sim

π/4-DQPSK

Differential phase encoding, avoiding zero crossings

Real-World Applications

Bluetooth 2.0+EDR, PHS phones, TETRA police trunked communication systems. Differential modulation does not require complex carrier recovery circuits, suitable for mobile devices.

Experiment Steps

  1. Differential Encoding: Information is in phase changes
  2. Small Envelope Fluctuation: Suitable for non-linear amplifiers
