商品描述

Although the concept of Low Density Parity Check (LDPC) CODES ACCRUES FROM Robert G. Gallager's PhD thesis dated in 1962 and from his1968 book Information Theory and Reliable Communications, its renaissance was heralded by DJC MacKay, RM Neal: Good codes based on very sparse matrices, Lecture Notes in Computer Science, 1995 - Springer. Since then literally thousands of papers were written on the subject o LDPC codes, since they are capable f approaching the performance of turbo codes, while being license-free, which is an important benefit for industry as a whole. This momentum then led to the standardisation of numerous systems, which rely on LDPC codes and hence a book on the implementation-oriented aspects of LDPC codes, in particular to protography LDPC codes, which substantially reduce their storage requirements. The original LDPC codes relied on the pseudo-random allocation of the row- and column-parity checks, while pantograph LDPC codes design their allocation in a more sophisticated manner. The family of rateless codes is younger and less well documented, which justifies the treatment of this subject in the book.

商品描述(中文翻譯)

雖然低密度奇偶檢查碼(Low Density Parity Check, LDPC)的概念源自於羅伯特·G·加拉赫(Robert G. Gallager)於1962年的博士論文以及他在1968年出版的書籍《信息理論與可靠通信》(Information Theory and Reliable Communications),但其復興是由DJC MacKay和RM Neal所宣告的,該文獻為《基於非常稀疏矩陣的良好碼》(Good codes based on very sparse matrices),發表於1995年的《計算機科學講義筆記》(Lecture Notes in Computer Science)中,出版商為Springer。自那時以來,關於LDPC碼的文獻數量可謂成千上萬,因為它們能夠接近渦輪碼(turbo codes)的性能,同時不需要授權,這對整個產業來說是一個重要的好處。這股動力隨後導致了許多依賴LDPC碼的系統的標準化,因此本書專注於LDPC碼的實作導向方面,特別是對於平行圖LDPC碼(pantograph LDPC codes)的探討,這些碼顯著減少了其儲存需求。原始的LDPC碼依賴於行和列奇偶檢查的偽隨機分配,而平行圖LDPC碼則以更複雜的方式設計其分配。無損碼(rateless codes)家族較年輕且文獻記載較少,這也為本書對該主題的探討提供了正當性。
