论文摘要
研究了最近引入4D对称128-ARY调制格式的线性形状和非线性公差之间的性能权衡。数值模拟显示，相对于7B4D-2A8PSK格式，达到9.3％的增长，并且具有短块长度的概率形状的16QAM。
Performance trade-offs between linear shaping and nonlinear tolerance of the recently introduced 4D orthant-symmetric 128-ary modulation format are investigated. Numerical simulations show 9.3% reach increase with respect to the 7b4D-2A8PSK format and probabilistically-shaped 16QAM with short blocklength.
