| 中文摘要 | A semi-blind equalization method is proposed based on combination of adaptive and blind equalization techniques, which is more effective for optical signal processing in time-varied band-limited channel. The numerical simulation of Poisson noise OOK optical pulse signal in a band-limited channel using digital equalization techniques is performed, and the results are compared. The semi-blind equalization matchs the channel faster and sustains convergence were identified. In addition, the wavelet de-noise technique is introduced in the de-nosing area of optical signa process. The criteria of choosing wavelet basises is obtained that smooth wavelet soft threshold method is better. The corresponding numerical simulation is also conducted. |
