C8-pi4demo
这个例子将产生并显示pi/2 DQFSK系统中的一些重要信号,仿真这个系统并产生图形输出的MATLAB程序在文件夹中给出。在MATLAB的命令提示符下输入程序名c8-pi4derno后,会绷现一个菜单,用户可通过这个菜单选择以下七个选项中的一个(产生一个图形后,击空格键会显示菜单以便作另一个选择)
1.滤波前的pi/4 DQPSK信号星座图
2.滤波前的pi/4 DQPSK眼图-
3.滤波后的pi/4 DQPSK信号星座图
4.滤波后的pi/4 DQPSK眼图
5.滤波前的同相和正交信号
6.滤波后的同相和正交信号
7.退出程序(返回MATLAB命令提示符)
读者应该仔细研究文件夹中的内容,因为它阐明了很多常见的后处理过程,而且,产生各种图形的代码可用于其他仿真程序的后处理器。
(It is very difficult to describe the MATLAB procedure in english.)

Fractional_Delay_FIR
功能描述: 小数延迟FIR滤波器,对参考阵元信号signal_ref进行
length(tau) M次延迟,分别得到M个阵元的采样信号
关键问题: 若τ 1.2Ts,则Delay(i) 2,tau_valid(i) 0.2Ts
若τ 0.6Ts,则Delay(i) 1,tau_valid(i) -0.4Ts
当tau_valid(i)>0或<0时,从卷积后的数据y_FIR_delay中取值启示位置不同
函数能够实现输入任意延时tau,输出信号波形与理想波形之间误差很小。( Description: fractional delay FIR filter array element of a reference signal signal_ref performed length (tau) M delay times, respectively, to obtain a sample signal array element M key question: if τ 1.2Ts, then Delay (i ) 2, tau_valid (i) 0.2Ts if τ 0.6Ts, then Delay (i) 1, tau_valid (i) - 0.4Ts when tau_valid (i)> 0 or < 0, the volume data y_FIR_delay product after the Enlightenment values at different positions function can be realized enter any delay error between tau, the output signal waveform and the ideal waveform is small.)
