论文摘要
我们介绍了在现成的通用图形处理单元（GPU）上实现的灵活的软件定义的实时多元调制格式。柔性接收器能够处理2 GBAUD 2-，4-，8-和16-ARY脉冲振幅调制（PAM）信号以及1 Gbaud 4-，16-和64-ARY的振幅振幅调制（QAM）信号，后者使用Kramers-Kramers-kronig（kK）coliver检测到后者。为背靠背显示了实验性能评估。此外，通过使用JGN高速R＆D网络测试床，在91公里电场剥离的光纤和可重构光学载体多功能器（ROADMS）的传输后，可以评估性能。
We introduce a flexible, software-defined real-time multi-modulation format receiver implemented on an off-the-shelf general-purpose graphics processing unit (GPU). The flexible receiver is able to process 2 GBaud 2-, 4-, 8-, and 16-ary pulse-amplitude modulation (PAM) signals as well as 1 GBaud 4-, 16- and 64-ary quadrature amplitude modulation (QAM) signals, with the latter detected using a Kramers-Kronig (KK) coherent receiver. Experimental performance evaluation is shown for back-to-back. In addition, by using the JGN high speed R&D network testbed, performance is evaluated after transmission over 91 km field-deployed optical fiber and reconfigurable optical add-drop multiplexers (ROADMs).
