Performance Comparison of PS Star-16QAM and PS Square-Shaped 16QAM (Square-16QAM)

Performance Comparison of PS Star-16QAM and PS Square-Shaped 16QAM (Square-16QAM)

We investigate and compare the performance of star-shaped 16-ary quadrature amplitude modulation (Star-16QAM) and square-shaped 16QAM (Square-16QAM) in the probabilistic shaping (PS) and uniform schemes with coherent detection. With the help of PS technology, the bit error ratio (BER) improvement ac...
