具有同步误差的通道的两个最常见模型是具有参数p(BDC P)的二进制删除通道 - 一个通道,其中每个码字的每个位均被概率p删除I.I.D,而Poisson重复通道则带有参数λ(PRCλPRCλ) ) - 基于同步字符串的先前构造的通道是重复的泊松(λ),其速率远低于这些通道的容量[6,9]在撰写本文时,BDC基于极地代码的更先进的方法[23],我们提出了一种串联同步代码的新方法,并使用它来构造简单和高效的编码对于两个几乎最佳速率的渠道。
Two of the most common models for channels with synchronisation errors are the Binary Deletion Channel with parameter p (BDC p ) – a channel where every bit of the codeword is deleted i.i.d with probability p , and the Poisson Repeat Channel with parameter λ (PRC λ ) – a channel where every bit of the codeword is repeated Poisson( λ ) times. Previous constructions based on synchronisation strings yielded codes with rates far lower than the capacities of these channels [6, 9], and the only efficient construction to achieve capacity on the BDC at the time of writing this paper is based on the far more advanced methods of polar codes [23]. In this work, we present a new method for concatenating synchronisation codes and use it to construct simple and efficient encoding and decoding algorithms for both channels with nearly optimal rates.
