Transmit power optimization for full duplex decode-and-forward relaying

, 2013
Full duplex transmission is a promising technique to enhance the capacity of relay communications. In this paper, we investigate the optimum transmit power allocation for full duplex decode-and-forward (DF) relaying systems.

Eficiência energética e throughput seguros em decode-and-forward seletivo com alocação de potência distribuída [PDF]

, 2015
We investigate the secure energy efficiency and throughput in cooperative wireless communications systems, in which a pair of legitimate users (Alice and Bob) are assisted by a relay node and the communication occurs in the presence of a passive ...

High-Performance Cooperative Demodulation With Decode-and-Forward Relays

, 2007
Cooperative communication systems using various relay strategies can achieve spatial diversity gains, enhance coverage, and potentially increase capacity. For the practically attractive decode-and-forward (DF) relay strategy, we derive a high-performance

A Novel Relay Selection Criterion for Decode-and-Forward(DF) Cooperative Communication Systems

, 2014
合作式通訊網路系統在這個世紀逐漸的成為一種熱門研究方向，在合作式通訊網路系統當中，放大前送式還有解碼前送式是其中二個較為熱門的討論區域。 在這篇論文當中，我們在解碼與前送的這個系統下，基於我們所使用的正弦信號，提出一種新的上界來分析符號錯誤率的性能，從模擬圖當中，顯示出我們所提出的這個新的方法，比起另外二種系統 調合平均數法則 以及 最大最小選擇法 更能夠選出好的中繼器來傳送信號。Cooperative system network has been most popular in the ...
