Here is my little problem in animated frames.
What you are seeing is already DQPSK. Displayed is the signal
constellation for one OFDM frame, 75 symbols. The code was posted earlier.
The problem: The (differential!) signal constellation has a constant phase
offset for each OFDM symbol. Why? What to do about it?
