Modified QPSK Partition Algorithm Based on MAP Estimation for Probabilistically-Shaped 16-QAM
Jin Hu, Zhongliang Sun, Xuekai Xu +4
Probabilistic shaping (PS) is investigated as a potential technique to approach the Shannon limit. However, it has been proved that conventional carrier phase recovery (CPR) algori…

Capacity limit for faster-than-Nyquist non-orthogonal frequency-division multiplexing signaling
Ji Zhou, Yaojun Qiao, Zhanyu Yang +2
Faster-than-Nyquist (FTN) signal achieves higher spectral efficiency and capacity compared to Nyquist signal due to its smaller pulse interval or narrower subcarrier spacing. Shann…
