奇偶校验

A subcarrier arranging part (103) rearranges the data to be transmitted so that the systematic bit data will be arranged on a subcarrier in the vicinity of the center frequency and the parity bit data will be arranged on subcarriers in the vicinity of both ends.

副载波安排部件(103)对要发送的数据进行重排，使得系统位数据将被安排在中心频率附近的副载波上，而奇偶校验位数据将被安排在两端附近的副载波上。

This will determine how the paritybit will be set in each character.

这将决定了每个字符中的奇偶校验位是如何设置的。

The invention pertains to the communication technical field, and particularly relates to a design method of a low density parity-check matrix.

本发明属于通信技术领域，具体为一种低密度奇偶校验矩阵的设计方法。

The difference between the NOR and OR gate, on the one hand, and the NAND or AND gate, on the other, is to be noted.

为了减少代码在传输、接受以及其他处理过程中出现的错误，可以利用奇偶校验法来检查错误。

This essay introduces the master slave distributed computer system which uses the PC frame as the main frame,The even odd check as the multicomputer communication,and the 8031 monolithic computer as the slave computer .

本文介绍了以PC机为主机、以其奇偶校验位为多机通讯标志位、以 80 3 1单片机为从机的主从分布式计算机系统。

B. Now add a parity bit to each character. What is the probabity?

如果在每部分增加一个奇偶校验位，则此概率又是多少？

A modulating part (102) modulates the parity and systematic bit data.

调制部件(102)对奇偶校验位数据和系统位数据进行调制。

Then a single parity bit is calculated by the transmitter and sent after the data bits.

此后发送器计算得出一个奇偶校验位并将它在数据码元之后发出。

We will see later that this parity check methodis a simple example of a data link layer protocol.

我们稍候将从一个简单得数据链路层协议中知道奇偶校验的方法。

Low Density Parity Check codes have received more and more attention because of their excellent performance and low complexity decoding algorithm.

低密度奇偶校验(Low-Density Parity Check)码以其卓越的性能、极低的解码复杂度，在通信领域正得到越来越多的关注。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
