dc.description.abstract | 下一代通訊系統中要求更高的資料傳輸速率及更可靠的通訊,由於嚴重的路經衰減及干擾,位於蜂巢式網路邊界的用戶很難達到上述的要求。近來,Wang和Giannakis提出Complex Field Network Coding來增加多用戶通訊的吞吐量,然而,他們的方法不能為用戶提供差異化服務。其中,差異化服務是指保證基地台內的用戶能穩定的通訊。這些因素促使我們設計上行系統中繼器的功率分配來幫助用戶達到最小的誤碼率,我們更進一步引入最佳化方法來解決這個問題,模擬結果顯示,我們的方法可在蜂巢網路中提供差異化服務,除此之外,這個方法可以達到無干擾下單一使用者的效能。 | zh_TW |
dc.description.abstract | Higher data rates and more reliable communications are required in next generation communication systems. But the subscribers on the cellular boundary are difficult to attain these requirements due to the severe path loss and interference. Recently, the complex field network coding (CNFC) method has been proposed by Wang and Giannakis for multiuser communications to enhance the throughput. However, their method can't provide users with differentiated services. The differentiated services should guarantee that the subscribers have reliable communications in their correspond cellular networks. These considerations motivate us to design a power allocation precoder for a relay node employed in a uplink network to help subscribers, so as to minimize their BERs. We further introduce an optimization method to address this problem. Simulations show that our method can provide the differentiated service in the cellular network. In addition to providing users with differentiated service, our scheme always achieves the single user's bound that is based on a no-interference assumption. | en_US |
