Abstract: Multilevel polar-coded modulation exploits bit-level reliability diversity and can operate closer to coded-modulation capacity than bit-interleaved coded modulation. Existing constructions ...
Abstract: The underwater acoustic channel poses a significant challenge among communication mediums due to its time-varying dynamics, long multipath propagation, and severe Doppler shifts. Ensuring ...
