Precoded APPM Modulated Short Reach Optical System Based on Two-Dimensional Cyclic Iterative Coding
Опубликовано 2017-01-01Полный текстThis paper proposes and demonstrates a novel coded amplitude and pulse position modulation (APPM) scheme based on 2-D cyclic iterative coding (TDCIC) for short-reach optical systems. By adopting the precoding, better performance can be obtained because of the bits correlation. An experiment with 150...

Performance Comparison of PS Star-16QAM and PS Square-Shaped 16QAM (Square-16QAM)
Опубликовано 2017-01-01Полный текстWe 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...
