Simulating BPSK Costas Loop in Matlab

I am trying to implement BPSK demodulator in FPGA. First, I am modeling the system in MATLAB. Now, I am trying to design Costas Loop for carrier synchronization. … 311; plot(error); title('Phase Error'); subplot 312; plot(PhErr); title('Loop Filter'); subplot 313; plot(Theta); title('Control Signal \theta'); rf_signal comes from another script that generates BPSK
