In this paper, a new precoder for a coherent optical filter bank multicarrierwith offset quadrature amplitude modulation (FBMC/OQAM) system is proposed. Theprecoder is designed based on an iterative polynomial eigenvalue decomposition(PEVD) algorithm to jointly mitigate the inter-symbol interference (ISI) andinter-carrier interference (ICI). The PEVD algorithm is used to decompose apolynomial channel matrix into polynomial eigenvectors and eigenvaluesmatrices, then a precoder is designed based on the decomposed matrices. Theprecoder acts as a filter applied to each subcarrier and to its adjacentsubcarriers. In addition, a new adaptive optimum energy algorithm is proposedto truncate the insignificant precoder filter coefficients produced by the PEVDalgorithm and consequently reduce the computational complexity. A mathematicalmodel and algorithm for implementing the precoder are also presented.Robustness of the proposed precoder has been analyzed and compared to existingprecoder in optical channel with different dispersion effects. Numericalresults demonstrate that the new precoder significantly outperforms theexisting precoder in terms of error vector magnitude (EVM), bit error rate(BER), Frobenius norm of the error matrix, and computational complexity.
