Layer 2 frame cannot be processed by a receiver until all bits have been received by the receiver and a cyclic redundancy check ( crc ) has been performed 二層的幀必須等到所有比特全部接收通過crc (循環(huán)冗余校驗)效驗后才能被處理。
A layer 2 frame cannot be processed by a receiver until all bits have been received by the receiver and a cyclic redundancy check ( crc ) has been performed 二層的幀必須等到所有比特全部接收通過crc (循環(huán)冗余校驗)效驗后才能被處理。
( 4 ) cyclic redundancy check ( crc ) js a cyclic code often used redundancy information is added to every transport frame to detect the errors in it ( 4 )循環(huán)冗余校驗crc碼是常用的檢測錯誤的循環(huán)碼,通過在每個傳輸幀中加入冗余信息,而檢出其中的錯誤。
Thedly , the method of cyclic redundancy check ( crc ) in system softwar design was used to ensure the serial conununication reliability betwen contactless ic card and reader 第三,在系統軟件設計中采用crc校驗碼檢錯、出錯重發(fā)相結合的方法確保非接觸ic卡與讀寫器串行通訊可靠。
According the product code scheme proposed in nsfc projects , in that scheme , the product code has a special structure and uses the cyclic redundancy check ( crc ) to detect whether the information is decoded correctly 依據課題所研究的乘積編碼,利用其特殊構造,使用循環(huán)冗余校驗作為譯碼是否正確的判決,從而使乘積編碼的行列交替約束,實現約束維特比譯碼。
