Periodic modulation precoders allow blind identification of SISO channels from output second-order cyclic statistics, irrespective of the location of channel zeros, color of additive stationary noise, or the channel order overestimation errors. The performance of blind channel estimators relying on periodic precoders is investigated. Criteria for optimal designs of periodic modulation precoders are also presented.
