Abstract
In the context of redundant filter-bank precoders for blind second-order eq ualization, we consider the alpha -repetition/modulation scheme. Although i t is theoretically possible, the identification of a bandlimited communicat ion channel suffers from numerical problems if alpha is beyond a bound, If alpha is below this bound, simulation examples illustrate the robustness of the channel estimate.
