FPGA-Based Experimental Analysis of Fixed-Point Precision Impact on SOP Estimation in Coherent Communications Receivers
Geraldo Gomes, Rafael Vieira, Hani Kbashi +8
We experimentally evaluated the sensing-communication trade-off from the fixed-point precision MIMO equalizer using FPGA. At 7-bit, noise floor drops 100x and angular error 63%, bu…

Net 835-Gb/s/λ Carrier- and LO-Free 100-km Transmission Using Channel-Aware Phase Retrieval Reception
Hanzi Huang, Haoshuo Chen, Qian Hu +9
We experimentally demonstrate the first carrier- and LO-free 800G/λ receiver enabling direct compatibility with standard coherent transmitters via phase retrieval, achieving net 8…
