说明：  用matlab实现升余弦滤波器，完整的matlab程序代码。(Raised cosine filter with matlab implementation, complete matlab code.)

matlab编的可以画吸收光谱的程序，数据需要手动修改输入，从oring粘贴就行(the program could be used to draw the absorption of uv visible,the results of Gaussian.The data should be changed by hand.)

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.)

说明：  这是数字处理的发展总结，主要是OFDM中波束成向的技术总结(This is a summary of the development of digital processing, mainly into the OFDM technology in the summary of the beam)
