16-QAM CONSTELLATION AND MOD, DEMOD

To plot a 16-QAM signal constellation with annotations that indicate the mapping integers to constellation points. The code uses the scatterplot function to create the plot and the text function in MATLAB to create the annotations. We follow the foll

High-order modulation formats and advanced error correcting codes (ECC) are two promising techniques for improving the performance of ultrahigh-speed optical transport networks. In this paper, we present record receiver sensitivity for 107 Gb/s CO-
