Abstract :
Self-orthogonalization (SO) in the discrete frequency domain (DFD) and blind equalization using a stop-and-go (SAG) algorithm are studied for application to fractionally spaced equalizers. Problems arise when attempting a direct transportation to this case of the results known for synchronous equalizers is attempted; e.g., blind convergence is difficult to achieve. This is mainly due to the different properties of the input sequence correlation matrix. An algorithm is proposed that achieves blind convergence by combining the two techniques, suitably tailored for fractionally spaced equalizers.<>
