In a communication system (10), a receiving node (14) estimates bit error rate (BER) and the accuracy of the BER estimate based upon a single burst of a data communication signal (12). An appropriate decision rule (92) is selected (90) in response to the BER accuracy estimate. Different decision rules (92) are available to bias different decisions to favor desired outcomes. The bias is configured in response to the BER accuracy estimate. The selected decision rule (92) is evaluated (96) in view of an estimated BER. In response to this evaluation, a transmitting node (14) may be instructed (104) to increase or decrease its transmit power level. In addition, the BER may be measured, and the measurement used to verify the appropriateness of the decision rules (92).

A data communication system that maintains a desired link margin, comprising: a first node having a transmitter configured to transmit a data communication signal at a programmable power level; a second node having an RF section configured to receive said data communication signal; a bit error rate estimator, coupled to said RF section, for generating a first parameter that corresponds to an estimate of a bit error rate for said data communication signal; an accuracy estimator, coupled to said RF section, for generating a second parameter that assesses accuracy of said first parameter; and a controller coupled to said bit error rate estimator and to said accuracy estimator, said controller being configured to program said programmable power level in response to said first and second parameters, wherein said controller is configured to program an increase in said power level when said bit error rate estimate exceeds a decision point that varies in response to the accuracy of said bit error rate estimate.
