Patent ID: 10797729

Abstract:
A polar-code based encoder is used to perform a transfer of useful data to a polar-code based decoder via a Binary Discrete-input Memory-less Channel. The Divide and Conquer structure consists of a multiplexer having useful data bits and a set of frozen bits as inputs followed by a polarization block of size N=2L, wherein the polarization block of size N comprises a set of front kernels followed by a shuffler and two complementary polarization sub-blocks of size N/2 with a similar structure as the polarization block of size N but with half its size. A dynamically configurable interleaver is present between the shuffler and one and/or the other of the complementary polarization sub-blocks at each recursion of the Divide and Conquer structure. The configuration of the dynamically configurable interleavers is dynamically modified according to changes detected in the Binary Discrete-input Memory-less Channel.
