Abstract:
1. A method of selecting a data rate of a multicarrier communication channel comprising a plurality of individual orthogonal subcarriers, the method comprising: calculating signal to noise ratios (SNRs) for the individual subcarriers of the multicarrier communication channel from channel state information and a transmit power level; calculating a subcarrier capacity for the individual subcarriers from the SNRs; estimating a throughput for the multicarrier communication channel for each of a plurality of data rates from a sum of the individual subcarrier capacities and a predicted packet error ratio (PER) for each of the data rates; and selecting one of the data rates based on the estimated throughputs, wherein for a subsequent transmission, the individual subcarriers are to have a uniform modulation and code rate based on the selected data rate.
