我们提出了一种新的2通道任意波形发生器(AWG)的原型,产生复杂的信号星座与6位数字到模拟转换(DAC)高达72 GS/s的6 dB带宽为23 GHz。我们生成一个55-GBd根升余弦成形的单载波64-QAM信号。
We present a novel 2-channel arbitrary waveform generator (AWG) prototype, generating complex signal constellations with 6-bit digital-to-analog conversion (DAC) of up to 72 GS/s at a 6-dB bandwidth of 23 GHz. We generate a 55-GBd root-raised cosine shaped single-carrier 64-QAM signal.
