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.

正交信号校正法主要用于近红外光谱矩阵的预处理。其原理是将光谱阵与全氮含量阵正交,滤除光谱与因变量Y阵无关的信号,再建立定量校正模型,达到简化模型及提高模型预测能力的目的。(Orthogonal Signal Correction(OSC) removes variance in the X-block which is orthogonal to the Y-block. Such variance is identified as some number of factors (described as components) of the X-block which have been made orthogonal to the Y-block. When applying this preprocessing to new data, the same directions are removed from the new data prior to applying the model.)
