之前编的一个牛肉信息追溯系统中的牛肉店版，用来读取二维QR条码中的信息，并存储在Access数据库中，系统可实现记录添加，修改，删除，编辑，搜寻，以及搜集扫描枪信息等功能。系统的初始用户名和密码已附在说明文件中。-Beef shop in the version in the series before a beef traceability system, used to read the information in the two-dimensional QR code, and stor

QR分解是球形MIMO检测算法必不可少的环节,本代码采用m语言描述了QR分解分解具体怎么实现,而不是直接调用matlab内部函数,采用的是QR分解的脉动阵列结构,据此代码可轻易实现QR分解的FPGA设计-QR decomposition is an essential part of the spherical MIMO detection algorithm, the code uses QR decomposition decomposition m language to describe

一个2发1收的MIMO系统，接收端采用QR检测，最后仿出误码率和信噪比的曲线。信道在接收端已知-信道在接收端已知。-A 2-fa 2 collected MIMO system, using QR detection receiver, and finally like a bit error rate and signal to noise ratio of the curve. Channel known at the receiving end.
