Abstract: A transmission method or a transmission apparatus maps input information of K+n bits to a polar code, encodes the input information on the basis of the polar code, and transmits the encoded input information. The input information includes n parity check bits. n1 bits of the n parity check bits are mapped to least reliable bit positions of K+n bit positions of the polar code, and n−n1 parity check bits (where n−n1>0) are mapped to n−n1 bit positions having a minimum row weight among K+n−n1 bit positions excluding the n1 least reliable bit positions among the K+n bit positions.

Abstract: Disclosed are a method for dividing a carrying block of a Low Density Parity Check (LDPC) code and an apparatus therefor. The method for dividing a LDPC code of the present disclosure can obtain a high throughput by using a limited size of shifting network. Moreover, it is possible to prevent degradation in performance due to a minimum size of code block by performing shortening for a large size of code block while minimizing the number of code blocks. Furthermore, in selection of a minimum size of code block, since a minimum size of code block is selected on the basis of shortening for a relatively large size of code block, it is possible to increase the size of the minimum size of code block.
