A Low Complexity Pre-Distortion Method for Intra-channel Nonlinearity
Low Complexity Pre-Distortion Method Intra-channel Nonlinearity
2015/5/21
We propose a low complexity intra-channel nonlinearity pre-distortion method based on symbol rate operation. The method is experimentally verified under a 43Gb/s DP-QPSK coherent system, and the perfo...
Low-Complexity Two-Stage Carrier Phase Estimation for 16-QAM Systems using QPSK Partitioning and Maximum Likelihood Detection
Low-Complexity Two-Stage Carrier Phase Estimation 16-QAM Systems QPSK Partitioning Maximum Likelihood Detection
2015/5/20
A feedforward carrier phase estimation algorithm using a modified QPSK partition approach followed by maximum-likelihood (ML) detection is proposed. Results demonstrate complexity reduction by more th...
