This paper presents a blind frequency offset estimator for Polynomial Cancellation Coded Orthogonal Frequency Division Multiplexing (PLC-OFDM) signals with symbols overlapped in the time domain (Overlap PLC-OFDM). The estimation is carded out in the frequency domain. A frequency offset estimate is obtained by using a pair of demodulated subcarriers at the Discrete Fourier Transform (DFT) output. As no pilot tones are required for the estimation there is no loss in bandwidth efficiency. Simulations show that this estimator is an approximately linear function of frequency offset and has low variance.
