在本論文中,研究了多重跳躍合作式網路系統下結合技術,在對數常態衰減通道下,分析通道狀態訊息和固定增益繼電器在放大後傳送,探討選擇性合併與最大比例合併以及等增益合併利用精準的高斯正交方法與近似的改良式史瓦茲-業方法的效能,精準的高斯正交方法能提供精確的值,而另一方面,近似的改良式史瓦茲-業方法則是有效的減少運算量。比較精準架構與精準架構的trade-off。
In this thesis, study of combining methods for cooperative multi-hop systems. In the Log-normal fading channels, analysis Amplify and Forward (AF) methods for both Channel state Information (CSI) relays, and fixed-gain relays. Investigate Selection Combining (SC) and Maximum Ratio Combining (MRC) and Equal Gain Combining (EGC) use precise of Gauss Quadrature Rule (GQR) and Improved Schwartz-Yeh (I-SY) approximations of methods performance, precise framework can provide accurate values. On the other hand, approximation methods can reduce computation. Compare between GQR and I-SY trade-off.
