提出了一种利用低分辨率DAC克服带宽限制的新算法。我们分别使用4位和2.6位DAC演示了11 GHz以上的电背靠背32 Gbaud QAM-64和5GHz以上的光32 Gbaud QAM-4。
A novel algorithm is proposed to overcome bandwidth limitation using low-resolution DACs. We demonstrate electrical back-to-back 32Gbaud QAM-64 over 11GHz and optical 32Gbaud QAM-4 over 5GHz using 4 bits and 2.6 bits DACs respectively.
