• Closed-loop power control providing maximum capacity of the multicarrier channel with frequency selective Nakagami fading is investigated.Use of the famous Gallager channel capacity(water-filling)theorem with the assumption of limited transmitter power and independent fading in partial channels leads to the algorithm for their optimal power loading.Analytical expressions for the capacity of the multicarrier channel as a function of the number of its subchannels and the fading parameters are derived for the cases of Optimal Power Distribution(OPD)and Equal Power Distribution(EPD).The dependence of the capacity gain on the OPD system order, the fading depth and the average SNR due the optimal power control is obtained.Comparison of the power efficiencies of the systems with OPD and EPD is presented.
