dc.description.abstract協力式多樣傳送(Cooperative transmission)利用Relay的概念,不但提升整體系統的輸出量,也可有效節省功率及改善錯誤率。 在論文中提出兩種協力式多樣傳送的機制來有效執行協力式多樣傳輸,並且推導兩種機制的錯誤率上界,以及模擬OFDM(A)的系統中在低速移動的環境下,兩種協力式機制的效能比較。 第二部份為在AMC(adaptive modulation and coding)和AAS(adaptive antenna system)的支援下,提出能讓協力式傳輸更有效改善整體效能的機制。最後以802.16(e)的OFDMA的訊框結構為範例,提出ㄧLink adaption的方式,藉由在Base Station進行協力式傳送的評估決定傳送之機制,可有效使整體系統輸出量優於傳統的直接傳送方式。zh_TW
