gabor
- The real and imaginary components of a complex Gabor filter are phase sensitive, i.e., as a consequence their response to a sinusoid is another sinusoid (see Figure 1.2). By getting the magnitude of the output (square root of the sum of squared
Bode
- A Bode plot is a graph of the transfer function of a linear, time-invariant system versus frequency, plotted with a log-frequency axis, to show the system s frequency response. It is usually a combination of a Bode magnitude plot, expressing the magn

- 由于圆形阵列所具有的特性，使其正得到日益广泛的应用，但是圆阵方向图却具有 相对主瓣较高的旁瓣电平。为此，本文针对均匀圆形阵列的天线单元，应用遗传算法,分别 进行唯相位、唯幅度、相位-幅度的方向图综合方法，进行旁瓣电平的优化。仿真结果表明： 这些方法可有效地降低圆阵的旁瓣电平，为解决此类问题提供了有益的参考。 -Circular array of features, are being increasingly widely used, but the circular arra
Gabor-Magnitude-and-Phase-for-Face
- This paper proposes local Gabor XOR patterns (LGXP), which encodes the Gabor phase by using the local XOR pattern (LXP) operator. Then, we in-troduce block-based Fisher’s linear discriminant (BFLD) to reduce the dimensionality of the proposed des

- 对于城市环境中的高精度单频 GNSS 接收机而言，若考虑误差预报处理已抵消电离层误差，则地面传播环境所导致的多径效应将成为系统误差的主要因素。基于现有蜂窝通信的高分辨率信道估计结果，针对电波传播的幅度、相位、多普勒等特征提取信道响应函数，在极小误差范围内提供至 L 波段信号的线性特征映射-For multipath effects in urban environments with high accuracy single-frequency GNSS receiver, the foreca
