Physics-based ultra-wideband channel modeling for tunnel/mining environments

Understanding wireless channels in mining environments is critical for designing optimized wireless systems in these complex environments. In this paper, we propose a physics-based deterministic UWB channel model for characterizing wireless channels in mining/tunnel environments. Both the time domain Channel Impulse Response (CIR) and frequency domain channel transfer function for tunnel environments are derived in an analytical form. The derived CIR and transfer function are validated by RF measurements at different frequencies.
