Abstract
To estimate carrier frequency offset, a polynomial-rooting algorithm is proposed for symbols with constant modulus in OFDM systems. This algorithm makes use of the orthogonal subspace of the squared spectrum vector of the channel. Among the group of non-iterative methods, the algorithm offers the best accuracy.
