Abstract
Messages transmitted between a receiver (150) and a transmitter (240) are us ed to maximize a communication data rate. In particular, a multicarrier modulation system uses messages that are sent from the receiver to the transmitter to exchange one or more sets of optimized communication parameters. The transmitter then stores these communication parameters and when transmitting to that particular receiver, the transmitter utilizes the stored parameters in an effort to maximize the data rate to that receiver. Likewise, when the receiver receives packets from that particular transmitte r, the receiver can utilize the stored communication parameters for reception.< /SDOAB>
