How to use DWT for denoising complex data like OFDM symbol ?

I want to denoise complex signal but 'wdenoise' function must have input of type: double not complex.

If there are another function for denoising complex signal or any solution to avoid this problem.

So why not just denoise the real and imaginary parts separately, then combine them back into one complex array. Two calls instead of one. WTP?

Thank you for your help. I already tried this solution, but the biterror rate between the message and denoised signal is larger than the message and noisy signal.

I think this occured because denoising real and imaginary parts separately results new signal different from the original message.

I am also facing a similar problem. The BER of original is less than that of denoised. I have been trying hard to find a solution but did not get a suitable solution. Kindly share your suggestion if you got the solution.

Thanks in Advance

Hi

I have the same problem. Has been able to find a solution. My project is linked to the use of NOMA and I am stuck with that part.
