A method for controlling a data transmission rate of at least one transceiver in a wireless system, the transceiver including a transmitter and a receiver, the method including the steps of: determining a signal quality characteristic corresponding to a signal received at the receiver by measuring a difference between one or more reference constellation points and one or more received constellation points, the signal quality characteristic representing an estimation of signal degradation through the wireless communication channel; and modifying a data transmission rate of the transmitter as a function of the signal quality characteristic. The step of modifying the data transmission rate of the transmitter includes: determining lower and upper threshold levels representing reference minimum and maximum signal quality characteristics, respectively, corresponding to the data transmission rate; measuring a signal quality characteristic of the received signal; determining whether the measured signal quality characteristic is within the lower and upper threshold levels; maintaining the data transmission rate when the measured signal quality characteristic is between the lower and upper threshold levels; and increasing the data transmission rate when the measured signal quality characteristic is less than one or more lower threshold levels associated with one or more corresponding higher data rates.
