Abstract
Without channel state information available, universal designs of wireless OFDM transmitters and receivers offer performance that is robust to the underlying channel fades and the adopted signal constellation. We show that judiciously designed precoders with redundancy twice as long as the channel order are necessary and sufficient for guaranteed constellation- and channel-irrespective symbol recovery as well as for blind channel identifiability. Simulated comparisons of the novel precoders with zero-padded and cyclic-prefixed block transmissions delineate their relative merits.
