A Novel Polar Code Construction for Magnetic Induction-Based Wireless Underground Communications

Magnetic induction-based wireless underground communications (MI-WUC) is susceptible to interference from the diverse underground environment, leading to intricate channel distributions and low communication reliability. To address these challenges, we propose a novel polar code construction scheme specifically optimized for MI-WUC. Our scheme extends traditional channel polarization to incorporate complex channel polarization, allowing it to adapt to various underlying channels. Further, we provide a calculation formula for Bhattacharyya parameters and a construction method for polar codes. Simulations show that our scheme achieves higher transmission rates and broader communication ranges compared to general schemes.
