This document discusses optimizing bit loading in broadband power line communication networks. It describes using a greedy bit loading technique to maximize the raw bit rate given available transmission power constraints. The performance of bit loading is analyzed under different system parameters like load conditions, available power, and target error probability. Results show that raw bit rates increase with higher available power and decrease with higher load conditions and lower target error probabilities. Maximum raw bit rates of around 180 Mbps were achieved for the analyzed network model.
