Abstract
A communications system (30) includes a transceiver (42) for transmitting data from a plurality of bins. Specifically, the BER of the bins is substantially equalized by allocating data by determining a projected margin. The projected margin is calculated for each bin by subtracting a reference signal-to-noise value from an estimated bin signal-to-noise value. The reference signal-to-noise value is predetermined by theoretical calculation or empirical data and stored in a look-up table. Bits are allocated to the bin having the maximum projected margin. This provides the best BER without changing the transmit power.
