Binary erasure channel
二元消失通信路 -
4 di c, proietti d, telatar i e et al. finite - length analysis of low - density parity - check codes on the binary erasure channel. ieee trans
如果停止距離較小， ldpc碼在迭代譯碼下的錯誤概率曲線經常會出現所謂的"地板效應error floor 。 -
Cascaded low - density erasure codes are based on sparse random bipartite graphs. very efficient linear time encoding and erasure recover algorithms with the arbitrarily near erasure channel capacity performance of the codes with respect to the algorithms have made them one of the most optimal coding techniques up to now
基於稀疏隨機二部圖的級聯型低密度糾刪碼因其線性時間的編譯碼演算法和可任意逼近刪除通道容量限而成為目前最佳編碼技術之一。 -
In this paper, we study the stopping sets, stopping distance and stopping redundancy for binary linear codes. stopping redundancy is a new concept proposed by schwartz and vardy recently for evaluating the performance of a linear code under iterative decoding over a binary erasure channel. since the exact value of stopping redundancy is difficult to obtain in general, good lower and upper bounds are important
近年來，迭代譯碼的性能分析是低密度校驗ldpc碼研究領域的熱點問題之一， di等人在2001年指出：迭代譯碼在二元刪除通道bec中的性能可以由ldpc碼的停止集stopping set完全刻畫。
