| Abstract: |
| This paper introduces a novel equalizer based on the neural network. The complex-domain back propagation (BP) algorithm is derived to train the multilayer perceptron. Theoretical analysis and simulation results show that the proposed equalizer based on BP network has better performance than the conventional equalizers. |
