Theory of Periodically Time-Variant Linear Systems
Juan I. Bonetti, Agustín C. Galletto, Mario R. Hueda
In this work we provide a mathematical framework to describe the periodically time variant (PTV) linear systems. We study their frequency-domain features to estimate the output ban…
Design and Experimental Verification of a Novel Error-Backpropagation-Based Background Calibration for Time Interleaved ADC in Digital Communication Receivers
Fredy Solis, Benjamín T. Reyes, Damián A. Morero +1
A novel background calibration technique for Time-Interleaved Analog-to-Digital Converters (TI-ADCs) is presented in this paper. This technique is applicable to equalized digital c…
Linear Channel Estimation Based on a Low-Bandwidth Observation Channel with Unknown Response
Juan I. Bonetti, James Kunst, Damián A. Morero +1
We propose a novel system identification technique, based on a least-mean square algorithm, allowing for the estimation of a linear channel by using an unknown-response measurement…
Superscalar Parallel Carrier Phase Recovery with Transmitter I/Q Imbalance Compensation
Daniel R. García, Mario R. Hueda
We propose a superscalar parallel two-stage carrier phase recovery architecture to improve the performance of optical coherent receivers in the presence of Tx I/Q imbalance, Tx I/Q…
On the Application of Error Backpropagation to the Background Calibration of Time Interleaved ADC for Digital Communication Receivers
Fredy Solis, Benjamín T. Reyes, Damián A. Morero +1
This paper introduces a backpropagation-based technique for the calibration of the mismatch errors of time-interleaved analog to digital converters (TI-ADCs). This technique is app…
Adaptive Background Compensation of FI-DACs with Application to Coherent Optical Transceivers
Agustín C. Galetto, Benjamín T. Reyes, Damián A. Morero +1
This work proposes a novel adaptive background compensation scheme for frequency interleaved digital-to-analog converters (FI-DACs). The technique is applicable to high speed digit…
