1.3 μm all-VCSEL low complexity coherent detection scheme for high bit rate and high splitting ratio PONs
Fiber optics communications Vertical cavity surface emitting lasers Coherent
2011/5/21
Full 1.3 μm VCSEL-based simplified coherent detection receiver is demonstrated at 5 Gbps. Receiver sensitivity of -34 dBm is achieved providing link reach and splitting ratio extension for future pass...
A Low Complexity Pre-Distortion Method for Intra-channel Nonlinearity
Low Complexity Pre-Distortion Method Intra-channel Nonlinearity
2011/5/21
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
2011/5/20
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...
Low-Complexity, Blind Phase Recovery for Coherent Receivers Using QAM Modulation
Low-Complexity Blind Phase Recovery Coherent Receivers QAM Modulation
2011/5/20
We propose a new hybrid PLL/ML phase estimation method for low-complexity, blind phase recovery for M-QAM modulation. The linewidth tolerance of the proposed method is more than one order of magnitude...
