这是一个vb与s7200PLC自由口通讯的类模块，我自己工程中可以直接使用。它使用的通讯方式是西门子PLC的自由口通讯技术实现。在工程开发中有不错的表现，希望大家提出宝贵的意见。

采用Log-BP算法的LDPC码译码仿真程序，给出了不同信噪比下误码率和误包率的统计图，用matlab和C（c-mex）程序分别编写，有详细说明和注释。-The use of Log-BP decoding algorithm for LDPC code simulation program is given a different signal to noise ratio and bit error rate under the packet error rate of the statistical map, using matlab and C (c-mex) procedures, respectively, to prepare, has a detailed description and notes .

我们自己创建各个的头部,系统只是把它们发送出去. 在实例中,由于我们要修改我们的源IP地址, 所以我们使用了setsockopt函数,如果我们只是修改TCP数据,那么IP数据一样也可以由系统来创建的. -To create all our own head, the system only to send them out. In the example, because we have to modify our source IP address, so we use the setsockopt function, if we just amend the TCP data, then the IP can also be from the same data system to create the.
