Abstract :
To estimate carrier frequency offset, a polynomial-rooting-and-evaluation 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. The algorithm improves an existing non-iterative method.
