我搜集的关于把天线系统的文章。对于多数人多输出系统的八个天线系统进行总结。(eight antennas)

from Shortten DVB-S2 LDPC 64800 code into 8100 The program can produce the parity check matrix of DVB-S2 LDPC 64800 with short length code of 8100.

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.)
