Convoluntional code is a frequently used error - correction code 卷積碼是一種常用的糾錯編碼。
Reed - solomon ( rs ) code is a popular error - correction code and adopted in a variety of applications such as digital communications and digital storage systems 摘要里德所羅門碼是一種常見的錯誤更正碼,廣泛應(yīng)用于如數(shù)位通訊與數(shù)位儲存媒體中。
This technique can enhance the computing performance greatly . we also proposed a self - error - correction quantum storage architecture . it references the research on quantum error - correction code , and can build a reliable storage system 借鑒量子糾錯編碼的研究成果,提出了自糾錯的可靠量子存儲系統(tǒng)方案,為協(xié)同量子計算機(jī)提供了可靠的存儲系統(tǒng)。
In the aspect of communication in lunar ground , it uses the improved frame basing on hdlc , and adopts turbo as error - correction coding . as for lunar surface , because of the good channel , it uses the standard hdlc , and for the high speed video information , turbo is also used . 月地信道方面,選擇了基于hdlc的改進(jìn)幀格式,并采用turbo碼作為糾錯編碼;月表方面由于信道性能良好,采用標(biāo)準(zhǔn)hdlc的幀格式,對于高速率的圖像信息同時應(yīng)用turbo碼作為信道編碼。
Du pingzhou ( computer application ) directed by prof . sun huixian error - correction coding is used widely in satellite communications , mobile communications and data storing . reed - solomon code is one of the most useful error - correction codes , which has been accepted by ccsds aos as part of standard protocol 很多國際標(biāo)準(zhǔn)采用了rs碼,比如空間數(shù)據(jù)系統(tǒng)咨詢委員會( ccsds )在遙測信道編碼的建議書中將rs ( 255 , 223 )系統(tǒng)碼作為標(biāo)準(zhǔn)使用,高級在軌系統(tǒng)( aos )也采用了rs碼。
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(yàn)碼字分開傳送,信道狀態(tài)較好時只傳送信息碼字;信道變差時才要傳送校驗(yàn)碼字,校驗(yàn)碼字可單獨(dú)或與信息碼字一起將信息恢復(fù)出來,因此這種結(jié)構(gòu)對信道有較好的適應(yīng)性。
