Channel Coding Technologies in Next-Generation Wireless Systems

N ext-generation wireless systems are poised to de-liver unprecedented advancements in data rates, latency, and coverage compared to their predecessors. A key enabler for achieving these objectives is channel coding technology, which is critical in reducing error rates in wireless communications. To meet the demanding requirements of next-generation wireless systems, advanced channel coding techniques such as polar codes, low-density parity check codes, and Turbo codes have been proposed. These innovative coding schemes outperform traditional convolutional and Reed-Solomon codes in terms of error-correction capability and spectral efficiency. This paper presents a comprehensive overview of the essential channel coding technologies employed in next-generation (5G) wireless systems, specifically focusing on fifth-generation systems and beyond. Additionally, it highlights some of the significant research challenges and opportunities in this field, shedding light on the advancements needed to exploit the potential of future wireless communication networks fully. Compared to other survey papers in the field, our objective is to provide a more thorough summary of the most relevant channel coding techniques. This enables researchers and application developers to quickly learn the 5G channel codes. Additionally, we provide a comparison between the channel codes.
