矩阵分析与应用 (张贤达2)

一个1MHz的FIR低通滤波器。 ① 时钟信号频率16MHz; ② 输入信号位宽8bits，符号速率16MHz； ③ 要求在Matlab软件中进行FIR滤波器浮点和定点仿真，并确定FIR滤波器抽头系数； ④ 写出测试仿真程序。(A 1MHz FIR low pass filter. (1) The clock signal frequency is 16MHz; (2) The input signal has a bit width of 8 bits and a symbol rate of 16 MHz; (3) Floating-point and fixed-point simulation of FIR filter is required in Matlab software, and tap coefficients of FIR filter are determined. (4) Write the test simulation program.)

这个程序可以计算给定点处的小区信号范围覆盖。-is program computes a map of visibility from a selected point on a topography. It has been written to help the search for radio relay best location. Because it considers only direct line of sight, it gives a good estimation for possible radio link for short distances only (less than 10 km), neglecting curvature of the Earth, Fresnel zone and atmospheric refraction on radio waves propagation. The program computes the relative elevation angle of the mask for each point (the angle is null or negative if the point is visible). The function needs a digital elevation model Z and associated (X,Y) vectors or matrices of coordinates (same unit as Z), position of the point (X0,Y0), the antenna height H0 (for instance 4 m), and the hypothetic antenna height Ha on each topography points (for instance 3 m). When no output argument is given, the function plots a map of the results (color map of mask angles, and blank for visible points, see example screenshot). The s
