IEICE transactions on communications, 2006•search.ieice.orgA novel blind channel estimation scheme is proposed for OFDM systems employing PSK
modulation. This scheme minimizes the number of possible channels by exploiting the
constant modulus property, chooses a best fit over the possible channels by exploiting the
finite alphabet property of information signals, and achieves competitive performance with
low computational complexity. Results comparing the new scheme with the finite-alphabet
based channel estimation are presented.
