BCFO
We address the problem of blind carrier frequency-offset (CFO) estimation in quadrature amplitude modulation,
phase-shift keying, and pulse amplitude modulation
communications systems.We study the performance of a standard
CFO estimate, which consists of first raising the received signal to
the Mth power, where M is an integer depending on the type and
size of the symbol constellation, and then applying the nonlinear
least squares (NLLS) estimation approach. At low signal-to noise
ratio (SNR), the NLLS method fails to provide an accurate CFO
estimate because of the presence of outliers. In this letter, we derive
an approximate closed-form expression for the outlier probability.
This enables us to predict the mean-square error (MSE) on CFO
estimation for all SNR values. For a given SNR, the new results
also give insight into the minimum number of samples required in
the CFO estimation procedure, in order to ensure that the MSE
on estimation is not significantly affected by the outliers.

Weighted-Average-interpolation
加权平均法是DEM移动内插法的特例，是一种简化的逐点内插法。它是先以内插点为中心，确定一个取样窗口，然后计算落在窗口内的采样点的特征值的平均值，作为内插点的特征值的估值，(The weighted average method is a special case of the DEM mobile interpolation, a simplified point-by-point interpolation. It is the first interpolation point as the center, to determine a sample window, and then calculate the average of the characteristic values of the sample points falls within the window, the valuation of the points of the feature value as the interpolation,)
