Recent results have shown that periodic modulation precoders allow blind estimation of FIR communication channels from the output second-order cyclic statistics, irrespective of the location of channel zeros, color of additive stationary noise, or channel order overestimation errors. The present paper extends these results to the more general blind problem of joint channel and carrier frequency offset estimation. The performance of a subspace channel identification algorithm is investigated in the presence of carrier frequency offset. Estimation of the frequency offset is simply obtained by exploiting the cyclostationary statistics of received data
