翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Orthogonal frequency-division multiple access ： ウィキペディア英語版 Orthogonal frequency-division multiple access Orthogonal Frequency-Division Multiple Access (OFDMA) is a multi-user version of the popular orthogonal frequency-division multiplexing (OFDM) digital modulation scheme. Multiple access is achieved in OFDMA by assigning subsets of subcarriers to individual users as shown in the illustration below. This allows simultaneous low data rate transmission from several users. == Key features == The advantages and disadvantages summarized below are further discussed in the Characteristics and principles of operation section. See also the list of OFDM Key features. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Orthogonal frequency-division multiple access」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
