Abstract

In the context of redundant filter-bank precoders for blind second-order equalization, we consider the α-repetition/modulation scheme. Although it is theoretically possible, the identification of a bandlimited communication channel suffers from numerical problems if α is beyond a bound. If α is below this bound, simulation examples illustrate the robustness of the channel estimate.
