2 . added long code and id operation function for canbus 2新增了can bus下:長編碼功能識別號作業功能。
If a retransmission is needed , additional redundant bits for error correcting are sent . concatenation of an inner code and an outer code may provide a high coding gain and the capacity of a long code to correct errors 級聯碼是將兩個或多個單碼級聯,在不增加譯碼復雜度的情況下,可以得到高的編碼增益,達到與長碼相同的糾錯能力。
We analyze how bit error rate ( ber ) , average delay , and throughput of the two structures vary with the maximal number of transmission attempts , and find that syndrome - ahead structure is suited for short codes with poor error - correction capacity , while syndrome - behind structure is suited for long codes with powerful error - correction capacity 分析了該harq的可靠性、時延和流量與最大重傳次數之間的關系,發現短碼長、糾錯能力低的碼宜采用前向校正子結構,而長碼長、糾錯能力高的碼宜采用后向校正子結構,二者具有互補性。
The cdna of subunit b was 1470 nucleotides long coding for 489 amino acids with a conservative atp binding site " 324 - sgsit - 328 " and a predicted molecular mass of 54 . 29 kda . amino acid sequence alignment analysis suggested that the v - h + - atpase b subunit of s . salsa had high homology with other reported v - h + - atpase subunit b . the h + - atpase subunit h from s . salsa was a hydrophilic protein with 465 amino acids and a predicted molecular mass of 52 . 8 kda , which was encoded by a cdna with 1398 nucleotides in orf . blast analysis indicated that the h + - atpase subunit h from s . salsa had a high amino acid sequence identity with those coming from plants , but had relatively low sequence identity with those coming from other species 鹽地堿蓬液泡膜h ~ + - atpaseb亞基是由1470個核苷酸編碼的長達489個氨基酸的多肽,分子量約54 . 29kda ,存在保守的atp結合序列“ 324 - sgsit - 328 ” ,與其他物種來源的v - h ~ + - atpaseb亞基具有較高的氨基酸序列相似性; h亞基為親水多肽,開放閱讀框長達1398 - bp ,編碼465個氨基酸殘基,分子量約52 . 8kda ,與植物來源的液泡膜h ~ + - atpaseh亞基具有較高的氨基酸序列相似性,而與其他物種來源的v - h ~ + - atpaseh亞基同源性較低; c亞基開放閱讀框為495 - bp ,編碼164個氨基酸殘基,分子量約16 . 6kda ,為一跨膜多肽,存在四個可能的跨膜區。
Low - density parity - check ( ldpc ) codes are a class of capacity approaching error - correcting codes . by using low complexity sum - product algorithm , ldpc codes can get near shannon limit decoding performance with almost all errors detectable . for long code lengths , ldpc codes can even outperform turbo codes 低密度校驗碼是一種能逼近shannon容量限的漸進好碼,在長碼時其性能甚至超過了turbo碼,其譯碼采用具有線性復雜度的和積算法,復雜度大大低于turbo碼,并且幾乎所有錯誤都是可檢的。
On condition that quality of picture restructured is insured , with a view to the motion estimation algorithms that costs the longest coding time , the method of prejudgment of zero motion vector is adopted in this paper , which makes about 50 percent motion estimation computation left out , so the encoding speed of encoder can be further increased 為了解決質量和實時性的矛盾,本方案在保證質量的前提下,針對運算時間較長的運動估計模塊,給出了零運動矢量提前判斷的方法,從而省去了約50的匹配塊搜索運算,提高了h
However , the long codes of random - generated ldpc are unfortunately sufferd from a defect of high encoding complexity ; especially the storage of generator matrix is considerably large during the encoding process . therefore , by way of making ldpc become realizable in the applications , it ’ s particularly important to search families of ldpc codes which may possess some algebraic structural properties 盡管如此,由于隨機構造的ldpc長碼在編碼上有著較高的復雜度,特別是編碼過程中還需要消耗大量的資源來儲存生成矩陣,因此為了讓ldpc碼能夠在實踐應用中成為可行,搜尋具有一定代數結構的ldpc碼就變得尤為重要。
