Abstract:
An apparatus comprising:means coupled to a first station for measuring a signal-to-noise ratio of a signal transmitted by a second station, said signal comprising a plurality of frames; means for adjusting a transmitted signal power of said signal as a function of a loop gain, said signal-to-noise ratio, and a signal-to-noise ratio threshold; means coupled to said first station for measuring a signal quality of the received signal; means for adjusting said signal-to-noise ratio threshold as a function of said signal quality and a signal quality threshold, comprising: means for increasing said signal-to-noise ratio threshold when a current frame has an error and a predetermined number of previous frames have no errors with a preselected minimum period between increases; and means for decreasing said signal-to-noise ratio threshold otherwise; means coupled to said first station for measuring a fading rate of said signal; and means for adjusting said loop gain as a function of said fading rate and a fading rate threshold.
