I am eager to get a matlab code.costas loop for QPSK.This is a difficult thing,and I wish author can help me.
For the BPSK Costas Loop example, may I ask why the demodulation only works when the quiescent (nominal) frequency for both VCOs are set to EXACTLY 1000 Hz?
The BPSK demodulation does not work for any other initial VCO (quiescient) frequency, such as 900 Hz or even 1500 Hz etc.
It appears that the simulation or model is flawed.
