Blind Signal Separation Based on Feed-forward and Feedback Neural Network

The algorithm based on feed-forward and feed-back NN combines both the algorithm based on feed-forward NN and the algorithm based on feed-back NN. It separates the signal blindly by modifying the feed-forward separating matrix and the feed-back separating matrix at the same time. It has both strong adaptability and fast convergence ratio. Finally, the algorithm was used to separate several typical radio fuse signal blindly, and the computer simulation wad made. The simulation result was ideal, indicates the algorithm to be effective.
