TLDR
In this article, a group-wise deinterleaving technique was proposed to ensure good communication quality when using an LDPC code to transmit data, which can be applied to data transmission or the like.Abstract:
This technology pertains to a data-processing device and a data processing method that make it possible to ensure good communication quality when using an LDPC code to transmit data. In group-wise interleaving, an LDPC code having a code length (N) of 16,200 bits and a code rate (r) of 10/15 or 12/15 is interleaved on a per-bit-group basis, each bit group being 360 bits long. In group-wise deinterleaving, the interleaved LDPC code is restored to the original ordering thereof. This technology can be applied, for example, to data transmission or the like using an LDPC code.read more

Coding scheme for a wireless communication system
TL;DR: In this paper, a base code is used in combination with common or variable puncturing to achieve different coding rates required by the transmission channels, and unpunctured coded bits are grouped into non-binary symbols and mapped to modulation symbols (e.g., using Gray mapping).
