    • 為了實現全雙工合作式通訊，在僅能使用半雙工裝置的前提下，我們提出 一種具有暫存功能的中繼站選擇機制。我們主要的想法是在每一個時間間隔中 選出不同的中繼站分別進行傳送與接收，但是這個想法會導致負責接收的中繼 站會受到負責傳送的中繼站的訊號干擾，這種干擾稱為中繼站間干擾，為了克 服中繼站干擾，參考現有的文獻，有效降低干擾的影響。透過模擬結果，我們 討論不同條件下的模擬的結果，其中包含暫存器的大小、中繼站的個數以及不同環境下的結果

    To enable full-duplex cooperative communications using half-duplex relays, a buffer-aided relay selection scheme based on amplify-and-forward (AF) is proposed in this work that can fully exploit the diversity gain. The key idea is to always select different relays to receive and transmit in the same time slot. Since the receiving relay is interfered by the transmitting relay, we apply a previously proposed interference cancellation scheme to mitigate the inter-relay interference (IRI). Through simulations, we study the performance of the proposed scheme under different scenarios and discuss the impact of various system parameters, including the buffer size, the number of relays, and the signal-to-noise ratio (SNR). Different buffer management trategies are also investigated.
