代码说明:

说明:  设计一个理想通信系统,实现信息字符流的传输。 发射器: 将消息(字符串形式)编码成一个符号序列; 用脉冲成形将串符号序列转变成模拟脉冲信号; 将模拟脉冲信号调制到载波信号上。 接收器: 对接收的信号进行采样; 解调信号成基带信号; 将信号恢复成字符串。(Design an ideal communication system, the realization information transmission of character flow. Emitters: < 1 > will news (string form) coding into a symbol sequence < 2 > by using a pulse forming will string of symbols into a simulation pulse signal sequences < 3 > will simulate the pulse signal modulation to carrier signal. Receiver: < 1 > of received signal sampling < 2 > demodulation signal into baseband signal < 3 > will signal back into a string.)

下载说明:请别用迅雷下载,失败请重下,重下不扣分!

  • abfilterandKalmanfilter
    本程序给出了ab滤波算法和Kalman滤波算法。 程序以叠加噪声的二维CV运动为例(包含轨迹突变情况),分别运用了ab滤波算法和Kalman滤波算法 对运动轨迹进行了跟踪,并比较了滤波性能。(This program give the Kalman filter algorithm and ab filter algorithm. Program uses the two-dimensional noise superimposed exercise as an example CV (including locus mutation), respectively ab filtering algorithm using Kalman filtering algorithm and Exercise carried out on the track to track, and compare the performance of the filters.)
