Bit Loading Algorithm Based on a Probabilistic Approach for HomePlug AV

In this paper bit loading algorithms that try to maximize the throughput, guaranteeing the overall BER below a fixed target, are investigated. In particular,the optimal solution is given and an approximation based on a probabilistic approach is detailed, providing a very simple implementation with negligible loss. The proposed solution is tested in the HPAV system, using a realistic power line channel model. Numerical results, in terms of throughput and complexity, show that the proposed solution is a good trade-off between performance and complexity.
