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.

The radially averaged power spectrum (RAPS) is the direction-independent mean spectrum, i.e. the average of all possible directional power spectra. This function computes and plots the RAPS of an input image. The function was written to produce the RAPS for square weather radar reflectivity images so you will have to relabel the plot axes and title to suit your needs. The radially averaged power spectrum provides a convenient means to view and compare information contained in 2D spectra in 1D

針對Mean Shift算法不能跟蹤快速目標(biāo)、跟蹤過程中窗寬的大小保持不變的特點(diǎn)。首先，卡爾曼濾波器初步預(yù)測目標(biāo)在本幀的可能位置；其次， Mean Shift算法在這點(diǎn)的鄰域內(nèi)尋找目標(biāo)真實(shí)的位置；最后，在目標(biāo)出現(xiàn)大比例遮擋情況時(shí)，利用卡爾曼殘差來關(guān)閉和打開卡爾曼濾波器。實(shí)驗(yàn)表明該算法在目標(biāo)尺度變化、遮擋等情況下對快速運(yùn)動的目標(biāo)能夠取得較好的跟蹤效果。
