在本論文中,我們研究一個以槽為基底,區塊衰落(Block-fading,BF)環境下的後大後傳送合作式架構。相較於之前假設在整個合作式框架中,均為常數通道(多個槽)。這邊我們所研究的策略是,假設為一個標準準靜態(classical quasi-static)區塊衰落通道(一個槽一個通道)。這個額外的自由度修改了傳統非正交放大後傳送的特性,並且產生一種新的區塊衰落非交放大後傳送(BFNAF)協定。

我們對所研究的策略探討其中斷機率。在實際應用上,我們對此研究策略提出了一個訊號處理架構,模擬這個信號處理架構來獲得位元錯誤率(BER)。此外,我們也對所提出的信號處理架構進行複雜度分析,以評估其執行情況。

In this thesis, we deal with an amplify-and-forward (AF) cooperative strategy in slot-based, block-fading environments. In contrast with previous schemes, which assume a constant channel during the cooperative frame (several slots), the studied strategy assume a classical quasi-static block-fading channel (constant for one slot). This additional degree of freedom modifies the behavior of the conventional nonorthogonal AF (NAF) schemes and generates a new block-fading NAF (BFNAF) protocol.
We evaluate the outage probability for the studied strategy. For real applications, one signal processing architecture of the studied strategy is proposed. We simulate the proposed signal processing architecture to obtain its bit error rate (BER), also, we perform complexity analyses of the proposed signal processing architecture to evaluate its implementation.
