Blind Frequency Offset Estimation Based on Phase Rotation For Coherent Transceiver
Conventional fast Fourier transform based frequency offset estimation (FFTFOE) algorithm is suitable for QPSK and 8/16/64QAM signals. However, due to the nonrectangular distribution of constellation points, the conventional FFT-FOE is not suitable for 32-QAM signal. In this paper, we report a factor...
