We propose a novel blind polarization de-multiplexing for Stokes vector direct detection (SV-DD) to decrease DSP complexity while increase the spectral efficiency. Effectiveness of the algorithm is proven via a 40-Gb/s SV-DD over 160-km SSMF transmission.
We propose a novel Stokes vector receiver (SV-R) with phase diversity based on 4 single-ended photo-detectors and demonstrate 80-Gb/s direct detection (DD) over 160-km SSMF transmission. OSNR sensitivity is compared among different SV-R DD schemes.
We propose a subcarrier reliability aware low-density parity-check (SRA-LDPC) soft-decision coding scheme for coherent optical orthogonal frequency division multiplexing (CO-OFDM) systems. The SRA-LDPC code takes consideration of varying signal-to-noise ratio performance among different OFDM subcarriers. At the SRA-LDPC encoder, flexible forward error correction is applied to different ranges of subcarriers...
We propose a single-carrier direct detection optical communication system using the signal-carrier interleaved scheme. Simulation with total data rate of 66.7Gbps and transmission distance of 100km fiber is demonstrated to evaluate its performance.
