Low Cost Transmitter Self-Calibration of Time Delay and Frequency Response for High Baud-Rate QAM Transceivers

Not Accessible

Your library or personal account may give you access

Abstract

We present a low-cost transmitter based self-calibration for IQ time delay and frequency response using only low-bandwidth components. Sub-ps timing correction and frequency response correction enable transmission of 400GE, 66Gbaud DP-16QAM and 44Gbaud DP-64QAM.
