A fully-blind fractionally-oversampled frequency domain adaptive equalizer

A frequency domain adaptive equalizer, operating with fewer than 2 Sa/Symbol is investigated. Steady state performance and dynamic operation are demonstrated without equalizer training. We find that the equalizer exhibits no penalty as low as 1.1 Sa/Symbol.
