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.

说明: 本程序展示了二维归一化互相关用于
  模式匹配和目标跟踪。该程序提示用户选择感兴趣的(ROI)的区域和对同类目标进行跟踪的数目。归一化交叉相关图表明,当值已超过设定的阈值时目标就已经确定。(This demo illustrates the use of 2-D normalized cross-correlation for
pattern matching and target tracking. The demo prompts the user to select the Region of Interest (ROI) and the number of similar targets to be tracked. The normalized cross correlation plot shows that when the value has exceeded the set threshold, the target has been identified.)
