Low density parity check ( ldpc ) code, which is a special case of error correction code with sparse parity - check matrix, has the performance very close to the shannon limit
Ldpc碼是一種特殊的具有稀疏校驗矩陣的糾錯編碼，其性能逼近香農限。這種碼具有實現復雜度低和數據吞吐量高的優點。 -
If no errors occur in it, the parity check part itself can retrieve the information by invertible process. if errors occur, the parity check part will be combined with the previously received information part to build an error - correction code, and try to recover the information. this kind of harq can match channel states very well
該harq將信息碼字和校驗碼字分開傳送，通道狀態較好時只傳送信息碼字；通道變差時才要傳送校驗碼字，校驗碼字可單獨或與信息碼字一起將信息恢復出來，因此這種結構對通道有較好的適應性。 -
As to the error control and data correction, the parity check and hamming code check solutions are provided also to guarantee the reliability of data transmission and improve the anti - jamming capability of the system
在差錯控制和數據糾錯方式上，也提供了奇偶校驗和漢明碼校驗的解決辦法，以保證數據傳輸的可靠性，提高系統的抗干擾能力。
