本論文探討非再生式無線通訊接引技術(Non-regenerative Relay hopping)分別在通道逾時資訊(Outdated Channel State Information)與長時遮蔽衰落效應(Long-term Shadowing)影響之系統效能分析。分析探討之項目分別為中斷機率(Outage Probability)與誤碼機率(Bit error rate; BER)。
論文採用雙階段(Dual-hop)全程接引方案在多重接引節點(Multi-nodes)作為系統之架構。並於選取接引節點後再行信號放大與轉發至接收站,先期進行節點選取策略與方法之探討,並於完成選取後經由系統模擬分析該兩項效能之表現,分別就逾時通道之交關聯函數對應所產生之逾時參數與長時遮蔽衰落效應之評估。後者方法將以柴比雪夫不等式(Tchebycheff Inequality)的高斯分佈作為遮蔽機率之演算,最後分析出總體系統效能之影響。
本論文成果將提供研究者簡易與有效的方法進行通道逾時與遮蔽衰落兩項效應對無線接引技術效能評估。

Performance analysis of the non-regenerative relaying system were investigated in terms of the outage probability and bit-error-rate (BER) performances under considering the effects of outdated channel state information (CSI) and long-term shadowing fading.
Accordingly, a dual-hop amplify-and-forward (AF) relaying system is proposed in association with two different relay selections which are (i) Max-min relay selection and (ii) Partial relay selection respectively. In order to simplify approximate the outage probability of log-normal fading, a Tchebycheff inequality is incorporated to using a Gaussian distribution in dB.
This paper is therefore motivated to provide a simple and efficient approach to evaluate the impacts on shadowing effects. Meanwhile, the impact on the outdated CSI was also presented in comparison of both relay selection schemes.
