Hello there, I am using GNU-Radio to simulate a QPSK modulation. There is also a SRRC filter with alpha = 0.5. If I look at the constellation after the SRRC filter, I see eight points, four in the expected I/Q positions, and other four like they were rotated of 45 degrees wrt the previous ones. Why this is happening? Thanks for your useful videos!

Hi Prof Iain Collings would you please try this transmission while using PHYDYAS prototype filter instead of root raised cosine and make another video. I think the result would be interesting.

And I have another question. would you please let me know what type of information can be understood or extracted from the eye diagram?
