Hi,
How can building constant modululs algorithm (CMA) in matlab (m file ) connected with design 4QAM in Optisystem , to handling the dispersion when increase the length of fiber
thanks 🙂

      You can find Matlab file for DSP. It contains CMA algorithm for QPSK. It is easy to develop it to QAM.
      100 Gbps DP-QPSK

      By the way CMA is not for Dispersion compensation as my knowledge.
