access icon free Modified downhill simplex method for fast adaption of optical filters in optical communication systems

The authors propose a control method based on the downhill simplex (Nelder–Mead) method for adaptive optical filters used for channel equalisation in optical communication systems. The performance of this method is compared to gradient methods in numerical simulations. The results show that the proposed method can adapt the filter to more rapid changes of the transmission channel than the gradient methods.
