A unified resource-pool architecture for high-dimensional direct-detection optical communication
Jingze Liu, Zhijuan Gu, Xinyang Yu +12
Increasing optical communication capacity without proportionally increasing receiver complexity remains a key challenge for direct-detection links. Conventional systems typically a…
