| Abstract(in English) | In this paper, iterative modified constant modulus algorithm (I-CMA) is proposed for blind dispersion equalization on Fourier-encoded optical code division multiplexing (FE-SOCDM) signal transmission. Firstly, effectiveness of the proposed I-CMA is investigated via numerical simulations with quadrature phase shift keyed (QPSK) signals under the presence of normally-distributed noise. Numerical results show that I-CMA with 10 iterations improves error vector magnitude (EVM) of the QPSK signals up to 5% while the improvement by 50 iterations is strongly depending on the quality of the original input QPSK signals. The experimental results of a single channel or two channels of the 10-Gbit/s QPSK FE-SOCDM signal transmission through a single mode fiber (SMF) are presented. I-CMA with 10 iterations could equalize chromatic dispersion over 105 km of SMF, and the two-channels of 10Gbit/s QPSK FE-SOCDM signal transmission, with a spectral efficiency of 2bit/s/Hz, was successfully demonstrated by utilizing a combination of coderwords c_1 and c_2. |
