Abstract
ABC (Auto Bias Control) technique for QAM (Quadrature Amplitude Modulation) transmitter is demonstrated. 16-QAM (10G baud) is generated and controlled using a single IQ modulator and asymmetric bias dithering technique. Measured penalty is 0.3 dB.
摘要
展示了用于正交幅度调制（QAM）发射机的自动偏置控制（ABC）技术。使用单个同相正交（IQ）调制器和非对称偏置抖动技术生成并控制16-QAM（10吉波特）。测量到的代价为0.3分贝。
