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.
