Block transmission systems using OFDM (orthogonal frequency domain multiplexing) are known for their computational efficiency in dealing with time dispersive, wireless channels. The efficiency relies primarily on data blocking by cyclic prefixing and on the exploitation of the eigenvalue decomposition of circulant channel matrices. Based on other blocking techniques and on other efficient matrix decompositions,...
In this paper, the minimum mean square error (MSE) convergence of the RBF equalizer is evaluated and compared with the linear equalizer based on the theoretical minimum MSE. The basic idea of comparing these two equalizers comes from the fact that the relationship between the hidden and output layers in the RBF equalizer is also linear. For the purpose of theoretically evaluating exact minimum MSE...
