A Constant-Factor Approximation for Wireless Capacity Maximization with Power Control in the SINR Model [PDF]
, 2010 In modern wireless networks, devices are able to set the power for each transmission carried out. Experimental but also theoretical results indicate that such power control can improve the network capacity significantly.

The BER Performance of the LDPC-Coded MPPM over Turbulence UWOC Channels
Photonics, 2022 Turbulence-induced fading is a critical performance degrading factor for underwater wireless optical communication (UWOC) systems. In this paper, we propose a quasi-cyclic (QC) low-density parity-check (LDPC) code with multiple-pulse-position modulation (
