This letter considers a single-input single-output powerline communication (PLC) system employing quadrature phase-shift keying (QPSK) modulation scheme under Rayleigh fading and Nakagami-m noise ...

Results demonstrate successful data transmission at depths up to 1.5 meters, analyzing the trade-offs between operating frequency, modulation scheme, burial depth, signal-to-noise ratio (SNR), and ...
