Polarization-Adjusted Channel Coding for Lower Receiver Complexity

The patent segments the set of information bits into multiple subsets, where each subset corresponds to a specific polarization level. Each subset is encoded separately using appropriate channel coding schemes, and then all encoded subsets are concatenated to form the final codeword. This segmentation allows the receiver to process different subsets independently, significantly reducing computational complexity while maintaining communication reliability through polar code's inherent error correction capabilities.

The patent applies different channel coding schemes and coding rates to different subsets of information bits based on their corresponding polarization levels. Each polarization level has distinct channel characteristics, and the encoder selectively applies appropriate coding schemes (such as LDPC, Turbo, or Polar codes) and adjusts coding rates to match the channel conditions at each level. This local optimization enables efficient throughput scaling without uniformly increasing computational complexity across all data streams.

The patent introduces polarization levels as an additional dimension for organizing and processing information bits. By mapping different subsets of information bits to different polarization levels, the system creates a multi-dimensional encoding structure where each dimension (polarization level) can be independently encoded with appropriate schemes. This dimensional organization provides encoding flexibility and reliability improvement while managing device complexity through structured, modular processing.
