Hello, I am trying to reproduce Figure 3 in your paper, but the result of my reproduction is not consistent with the 16QAM result in your paper. At present, we have not found the reason, hope to get your help!

Hello! I updated the GitHub code. The constellation set must be scaled to reproduce the results in the following paper. Joint Receiver Design for Integrated Sensing and Communications ( https://ieeexplore.ieee.org/document/10121420/)

Thank you.

Thank you very much for your reply, I am trying the method you said. In addition, I would like to ask if you can provide some help for the part B. Optimal Design: Non-IC. I tried to reproduce this part, and the following is my code, but the result is incorrect: % Non-IC MMSE estimate num = 0; denom = 0;

for k = 1:M ref = h_c(:, jj) constellation(k); Exp_term = exp (rxSig - ref) '(0.5 inv (R) (rxSig - ref)); num = num + (rxSig - ref) * exp_term; denom = denom + exp_term; end

% Calculates an estimate of alpha alpha_hat_NIC(jj) = (g' inv(R)) (num / denom); end

% Calculates the MSE and stores it mse_NIC = [mse_NIC, immse(alpha, alpha_hat_NIC)];

Hello, Unfortunately, I only implemented the first part.

Thank you.

Sir, May I know the logic of choosing constellation(k) in the refernce signal instead of using the s(n) as mentioned in the paper. When I tried with s(n), here the transmitted communication signal it not working and getting a constant line BER and reverse MSE. ref = w_H Q h_c(:, jj) * s_t_commsig;

may I know the logic behind using constellation(k).

I tried so far and getting stuck. Please share.

Thank you.
