近年來,有越來越多合作式通訊的研究。在雙向傳輸合作式通訊中有中繼站來幫助使用者互相交換彼此的資訊。我們主要針對放大轉發來做研究,放大轉發也就是中繼站只是把收到的訊號加以放大在傳遞給使用者。我們也考慮一個有效率的方法來增加頻譜的使用效率,藉由全雙工模式在每個端點使得這些端點可以同時接收資料還有傳遞資訊在相同的頻率上。在全雙工模式下,每個端點會受到自己的訊號干擾可能會導致系統效能變差。因為這些端點沒有正確的回授通道狀態,即使在近年來的自我干擾消除技術也無法保證可以完全消除,因此會有剩餘的自我干擾存在影響系統的效能。我們主要探討傳輸的功率與自我干擾消除能力因子的關係,因此我們可以得到合理的選擇傳輸的功率去得到最好的系統性能。此外,我們提出極限的平均SNR 與SER 在給定通道式相互的。最後我們跑模擬驗證我們的結果。

Recently, there are more studies working on the cooperative communications.
There exist a relay to help the users exchange its information by cooperating in a two-way relaying system. In this work, we focus on the amplify-and-forward pro-tocol, i.e., the relay just ampli es the signal transmitted by the users and then broadcasts it to the users. We also consider an efficiency way to enhance the spec-trum efficiency by applied full-duplexity on each node, that is these nodes in our system could transmit and receive signal at the same time and the same frequency. With the full-duplexity, these nodes suffer from its self-interference would lead to a bad performance. It''s because the nodes didn''t have the perfect loopback channel state information. Even with the recent advance self-cancellation techniques could not guarantee perfect cancellation. Hence, a level of the residual self-interference persists and would cause the system performance degraded. We mainly investigated the relation between the transmission powers and the cancellation factor, and we could obtain the reasonable transmission powers to get a best performance in the full-duplexity system. Furthermore, we proposed the limiting average SNR and SER under the case that the channels are reciprocal. Finally, we con rm our analysis with simulations.
