QC-LDPC码的编码和译码程序
///请注意:一定要看到最后!关于QC-LDPC码的编码和译码程序,之前上传了编码程序,这个是在其基础上,又添加了译码模块,和一个主程序main.m,主要是看迭代次数或码长或码率对误码率的影响。这个matlab运行时间会有点长,要有耐心。程序和前面的一样,简单易懂!!!切记是运行main.m程序,看清楚奥。//资源如果可以的话,记得好评哦,毕竟是自己辛辛苦苦做出来的。谢谢你们了!

STM32无刷无感电机驱动
基于STM32R8T6的无刷无感电机驱动,由原子的DMA的ADC基本代码修改而来,主要内容包含在control.c中,外部驱动使用的是BTS7971,使用MOS也行,ADC一直采样判断过零。有电流环控制,但是注释了,修要的把注释去掉就行。代码采用三步启动方法启动电机,有延时30电角度换向,是参考MK电调的说明文档(无刷无感直流电机攻略@timegate墨鸢)代码纯手写,可以私信问我,交流为主,但是我可能不会及时回复。

HBase为数据库的web系统
随着海量数据和云计算的发展,Hadoop集群得到了越来越广泛的应用。而HBase作为Hadoop集群的数据库同样在很多场景中大显身手。同样Hadoop集群的稳定性需要得到实时的监控。存储资源、计算资源、网络资源等发生阻塞或者错误需要及时告知集群管理员。本文实现了基于HBase的网站告警系统。本文中所开发的系统分为告警记录显示、告警记录查询、告警记录确认、告警记录入库、告警记录删除等模块。本文依照需求分析、概要设计、详细设计的软件开发步骤实现了一个基于HBase的网络告警系统。

k均值聚类分析matlab代码
基本思想:首先任意选取K个聚类中心,按最小距离原则将各模式分配到K类的某一类;不断计算聚类中心和调整各模式的类别,最终使各模式到其判属类别中心的距离平方之和最小。
