Abstract

The sixth generation (6G) wireless communication system will improve the key technical indicators by one to two orders of magnitude, and come with some new features. As a crucial technique to enhance the reliability and efficiency of data transmission, the next-generation channel coding is thus confronted with new challenges in terms of complexity, latency, performance. This article supplies an overview of the potential channel codes for 6G communications. In addition, we explore to develop next-generation channel codes based on lowdensity parity-check (LDPC) and polar frameworks, introducing a concept named generalized LDPC with polar-like component(GLDPC-PC) codes. The codes have exhibited promising error correction performance and manageable complexity, which can be further optimized by specific code design. The opportunities and challenges of GLDPC-PC codes are also discussed.
