Kawalan kuasa gelung tertutup yang menyediakan kapasiti maksimum saluran berbilang pembawa dengan frekuensi pudar Nakagami terpilih disiasat. Penggunaan teorem kapasiti saluran Gallager yang terkenal (pengisian air) dengan andaian kuasa pemancar terhad dan pudar bebas dalam saluran separa membawa kepada algoritma untuk pemuatan kuasa optimumnya. Ungkapan analitikal untuk kapasiti saluran berbilang pembawa sebagai fungsi bilangan subsalurannya dan parameter pudar diperoleh untuk kes Pengagihan Kuasa Optimum (OPD) dan Pengagihan Kuasa Sama (EPD). Pergantungan keuntungan kapasiti pada susunan sistem OPD, kedalaman pudar dan purata SNR kerana kawalan kuasa optimum diperolehi. Perbandingan kecekapan kuasa sistem dengan OPD dan EPD dibentangkan.

Lev GOLDFELD, Vladimir LYANDRES, "Capacity of the Multicarrier Channel with Frequency- Selective Nakagami Fading" in IEICE TRANSACTIONS on Communications,
vol. E83-B, no. 3, pp. 697-702, March 2000, doi: .
Abstract: 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.
