Bit rate maximization loading algorithm with mean BER-constraint for linear precoded OFDM

Résumé

The bit loading algorithms are proposed for orthogonal frequency division multiplexing (OFDM) and linear precoded {OFDM} under power spectral density and mean bit error rate (BER) constraints. These algorithms maximize the bit rate of the system while respecting a mean BER. The advantages of both linear procoded {OFDM} and classical {OFDM} are analyzed under different scenarios. It is shown that the proposed allocations perform better than the allocations under peak error rate constraint, while respecting a power spectral density constraint. The performance of the proposed algorithms is also better than the previously proposed algorithm under mean BER constraint. Moreover, it is observed that the algorithms for linear precoded {OFDM} under mean BER constraint have significantly lower computational complexity.
