OK this is my MATLAB code, it's taking tooooooooooo much time to execute. I actually halt it! LPF.mat contains LPF coeffs. rf_signal is produced in another m file and is found in workspace. NCO_model is the generated MegaCore MATLAB model. It produces one sin & cos sample for ...
MATLAB Online에서 열기 I use BPSK modulator and de-modulator and for error correction i use LDPC. input for LDPC decoder should be soft out put (likelihood) not real value but to calculate this soft bit I have problem. below is my code, how to calculate the soft bit out put a...

You might have to do matlab modelling to prove the concept in a simpler way away from BPSK as follows: 1)make your input a clean tone say at 0.1 Fs 2) apply NCO at -0.1 and do the rest as usual at the error detector I and Q should be dc (if all ok) and error should be...
