| dc.description.abstract | 本篇論文以交替性的方式發展出一種有效率之多重使用者位元負載演算法方式，適用於離散多頻系統。 有關干擾通道的模型亦被考慮進來，當每個用戶的傳送信號會引起其它用戶在接收上的干擾。 而此計畫目的是使得總傳送功率力能最小化且必須要滿意每個用戶的要求傳輸資料速度。 與現今所通用存在的演算法相比較，此所提議出的演算法可顯示出相當量的計算複雜度降低與可以忽視功率傳輸增加量，此將以模擬說明。 於此提議的演算方法能被用於離散多頻的系統， 但是假若考慮多重使用者的干擾通道模型的有線或是無線的通訊系統也能適用。 | zh_TW |
| dc.description.abstract | This thesis develops an efficient multi-user bit-loading allocation algorithm in an iterative fashion for discrete multi-tone systems. The model of the interference channel is considered, where the transmit signal from each user causes interference to the other users. The scheme aims to minimize the total transmit power while satisfying the required data rate of each user. The proposed algorithm is shown to greatly reduce the computational complexity of the existing algorithm with negligible amount of transmit power increment as demonstrated in the simulation results. The proposed methodology can be applied to the DMT-based system, but is also feasible for either wired or wireless communication systems with the model of the interference channel and another type of modulation scheme. | en_US |
