rakereceive_kron
本程序仿真了AWGN信道下,采用DS扩频对bpsk信号的影响,扩频码采用walsh码,扩频因子16;
接收端进行rake接收,然后分集合并,比较了三种分集方式对误码率的影响
从图像可以看出在扩频因子较高的情况下,最大比值合并与等增益合并性能相近(This program simulates the AWGN channel, using DS spread spectrum signal for bpsk influence spreading code using walsh code spreading factor 16
Rake receiver receiving end, and diversity combining, diversity compares three methods on the bit error rate of
As can be seen from the image in the case of higher spreading factor, the maximum ratio combining and equal gain combining similar performance)

VC(6.0)_ecg
用VC6.0编写的对话框程序,可以读取ECG(txt格式)数据,并画图。采用差分阈值法对心电信号进行R波的检测并显示R波检测的个数,效果较好。程序中也编写了一个滤波器对心电数据进行滤波。(VC6.0 prepared by the dialog box procedure, you can read ECG (txt format) data, and drawing. Differential threshold method ECG R-wave detect and display the number of R-wave detection, the better. The program also write a filter for filtering the ECG data.)

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.)
