【Other resource】 BCFO DL : 0: 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.

【Algorithm】 www DL : 0: 使用维纳分布进行瞬时频率估计用来校正电离层非线性相位污染带来的频带展宽-High-frequency (HF) sky-wave radar signals propagate to and from the target by means of the ionosphere. The difficulty in obtaining very narrow beamwidths at HF, and the long ranges involved, mean that the signal backscattered from the ground is often several orders of magnitude greater than the target echo. To resolve the target, coherent signal processing techniques are necessary, detecting the target echo by virtue of the Doppler shift caused by the target’s radial velocity. Unfortunately, movement of the ionospheric layer by which the radar signal has propagated often causes the clutter spectrum and target to spread in the frequency domain, rendering extended coherent integration pointless. The movement of the ionosphere can be regarded as producing frequency modulation of the radar signal, and thus if this modulation can be estimated the radar signal may be corrected for the ionospheric contamination. A technique using the complex argument of the first-order mo

【Mathimatics-Numerical algorithms】 COSFIRE DL : 0: COSFIRE是一个有效的滤波器，它可以自动的为图像画出轮廓，可以配置出gabor滤波器，配置一定的模糊参数和移位参数-A COSFIRE filter is automatically configured to be selective for a local contour pattern specified by a single example. The configuration comprises selecting given channels of a bank of Gabor filters and determining certain blur and shift parameters. Gabor filters are, however, not intrinsic to the method and nay other orientation-selective filters can be used. A COSFIRE filter response is computed as the weighted geometric mean of the blurred and shifted responses of the selected Gabor filters. It shares similar properties with some shape-selective neurons in visual cortex, which provided inspiration for this work.
