Need help with MSK demodulation implementation on MATLAB

Hello everyone,

I need help with MSK demodulation.

Actually I have done MSK modulation of a research paper named "MINIMUM SHIFT KEYING:

A SPECTRALLY EFFICIENT MODULATION" by "Subbarayan Pasupathy". I have also attached my MSK modulation results.

Please tell me is my MSK modulated signal correct?

Please also guide me how can I demodulate the my MSK modulated signal in MATLAB?
