Kerja ini membentangkan pendekatan berasaskan teori pengoptimuman ordinal dua peringkat untuk menyelesaikan masalah pemaksimuman throughput dengan kekangan kuasa penetapan sub-pembawa dan peruntukan kuasa dalam sistem uplink pemultipleksan bahagian frekuensi ortogon berbilang pengguna. Pada peringkat pertama, model kasar tetapi cekap digunakan untuk menilai prestasi corak tugasan sub-pembawa dan algoritma genetik digunakan untuk mencari melalui ruang penyelesaian yang besar. Pada peringkat kedua, model yang tepat digunakan untuk menilai s corak tugasan sub-pembawa terbaik yang diperoleh pada peringkat 1 dan membentuk subset pilih. Akhir sekali, yang terbaik daripada subset pilihan ialah penyelesaian yang cukup baik yang kami cari. Melalui pelbagai ujian, kerja ini menunjukkan kecekapan algoritma yang dicadangkan dan membandingkannya dengan kaedah heuristik yang lain.

Abstract: This work presents a two-stage ordinal optimization theory-based approach for solving the throughput maximization problems with power constraints of sub-carrier assignment and power allocation in multi-user orthogonal frequency division multiplexing uplink systems. In the first stage, a crude but efficient model is employed to evaluate the performance of a sub-carrier assignment pattern and the genetic algorithm is used to search through the huge solution space. In the second stage, an exact model is employed to evaluate s best sub-carrier assignment patterns obtained in stage 1 and form the select subset. Finally, the best one of the select subset is the good enough solution that we seek. Via numerous tests, this work demonstrates the efficiency of the proposed algorithm and compares it with those of other heuristic methods.
