labview程序，串口通信的例子，很值得大家参考，内有实时显示功能和回放功能，自定义设计传输参数，适合入门者学习

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.

引入PEG（Progressive-edge-growth）算法来构造适合线性时间编码的LDPC校验矩阵，译码时采用简化最小和Min-Sum译码算法实现简化译码．仿真结果表明，该方法能够构造适合LDPC码的线性时间编码的下三角校验矩阵日，并且用此方法构造的LDPC码性能非常接近原来PEG算法构造的LDPC码．同时通过采用最小和Min-Sum算法降低译码复杂度．-The introduction of PEG (Progressive-edge-growth) algorithm to construct suitable for linear time encoding of LDPC check matrix, decoding simplified when the smallest and the Min-Sum decoding algorithm decoding simplified. Simulation results show that this method can construct LDPC codes suitable for linear time encoding on lower triangular calibration matrix, and constructed using this method the performance of LDPC code is very close to the original PEG algorithm constructed LDPC codes. At the same time through the use of the smallest and the Min-Sum decoding algorithm to reduce complexity.
