Rate maximization loading algorithm for LP-OFDM systems with imperfect CSI

Résumé

The problem of bit rate maximization of a linear precoded orthogonal frequency division multiplexing ({LP-OFDM}) system is considered for imperfect channel state information. The discrete bit loading algorithms are proposed, which sustain the target bit error rate even under high mean square error (MSE) of estimation. The proposed scheme enhances the robustness of the system against noisy channel estimation without significantly compromising on the system throughput. The results are shown for a power line communication system using a well-known multipath channel model. It is shown that the proposed {LP-OFDM} allocation is more robust to estimation noise than {OFDM} allocations and provides higher throughputs even at high MSEs.
