- Channel coding is based on more recent developments by the scientific community : low - density parity - check codes are adopted . low - density parity - check codes were first introduced by gallager in 1960 . but due to the calculating effort in implementing , they were mostly ignored
其性能如此優(yōu)異的一個重要原因是采用了當今糾錯編碼技術發(fā)展的最新成果? ?低密度校驗( ldpc , low - densityparity - check )碼。 - A serially concatenated iterative scheme ( bpcm - id ) combining low - density parity - check codes ( ldpc ) with multilevel modulation is proposed . differ from other serially concatenated iterative decoding schemes , the whole iterative process of bpcm - id is divided into outer iteration and inner iteration to avoid too much errors feedback to the demapper which may cause severe degradation of decoding performance
論文提出了一種新的多級ldpc碼的概念、基本特性、構造準則和搜索算法,給出一種融合mlc / bicm的聯(lián)合編碼調(diào)制系統(tǒng)框架,與傳統(tǒng)mlc系統(tǒng)區(qū)別在于用一個多級ldpc碼取代多個分量碼。 - In detail , they are bit - interleaved coded modulation ( with iterative decoding ) , low - density parity - check codes and stf technology . by the performance analysis of bicm ( - id ) , which can make code and modulation optimal separately , and achieve maximum possible coding diversity as well as modulation gain , guidelines for its design and an easy algorithm for siso are proposed . design of capacity - approaching of ldpc codes and efficient encoding of them as well as several kinds of its decoding algorithms are investigated
具體的講，就是討論了基于比特交織的編碼調(diào)制技術，并給出了映射方式的設計準則以及核心模塊siso的一種簡單的f - map算法；研究了編碼最小漢明距隨碼長線性增加的ldpc碼的幾個方面的問題，包括接近香農(nóng)限碼子集的度分布對的設計、有效編碼器的實現(xiàn)和各種譯碼算法的優(yōu)缺點，并對基于ldpc碼的bicm應用于ofdm傳輸系統(tǒng)中的性能進行了仿真。 - The coding and decoding ideas of low - density parity - check codes on graphs are systematically summarized , and the density evolution theory is introduced . the two leading factors on the performance of ldpc codes , i . e . the degree distribution sequences and the girths of these codes , are analyzed in detail ; 2
