奇偶校验

In asynchronous transmission, a simple error-detecting scheme called parity can be used.

在异步传输时，一个简单的错误发现原来叫做奇偶校验被运用。

The most obvious disadvantage of asynchronous data transmission is the need for a start, parity, and stop bit for each transmitted character.

对于一个传送的字符，异步数据传输都需要起始位、奇偶校验和停止位，这是它最明显的缺点。

It is used to set baud rate, parity check, number of data bits, stop bit.

它是用来设置波特率，奇偶校验，数据位数，停止位。

Send and receive news : you can set ports, baud rate, parity and other parameters.

通过设置发送并接收消息：可以设置端口，波特率，奇偶校验等参数。

Fortunately,however,computer designers have developed a method for detecting such errors by add an extra check bit or parity bit to each 6,7,or 8-bit character represented in storage.Thus,as you can see,a total of 7,8,or 9-bits may actually be stored.

但幸福的是计算机设计者已研制了一种检测这种错误的方法，这就是，对在存储器中表示的每个6位、7位或8位字符增加一个附加的检查位或奇偶校验位，这样，正如你所看到的，实际存储的是7位、8位或9位。

To detect possible transmission errors, the receiver determines whether the received number of "1" bits is even or odd depending on the parity agreed.

为了检查可能传输中出现的错误，接收端将检查接收到的1的位的奇偶是否符合奇偶校验。

The embodiment of the invention provides a method for coding the low-density parity checking code, comprising the following steps: in the iteration for the time of k, the variable node corresponding to an overturn function meeting the preset condition is overturned; according to the preset parameter, the reliability of the overturned variable node is corrected; according to the sequence of the overturned variable node, the checkout sub sequence is determined so as to output the coding result.
