摘要: 
適應性調變可以用來增強在多重節點之解碼前送式合作式通訊
系統的系統效能。然而,他的理論極限在這樣的一個系統依然尚未被
了解。因此,我們考慮兩種不一樣的理想協定來研究這樣的問題。第
一種協定可以達到最大的速率而第二種協定則是專注在達到最好的
效能。調變階層的分佈,平均速率和效能在這兩種協定裡的理論結果
可以被推倒出來並且經過電腦模擬可被確認。我們也提議一個機制來
選擇調變結構以及幫忙傳送訊號的中繼傳送節點,在盡可能達到最大
平均速率和效能的同時去滿足中斷傳送機率的需求。這項被提議的機
制也會與基於訊雜比的機制來做比較。在與基於訊雜比的機制去比較
效能的同時,我們所提議的機制可以提供更好的平均速率。

Adaptive modulation has been shown to increase the system efficiency of multinode
decode-and-forward cooperative communication systems. However, its theoretical
limitation in such a system still remains unknown. In this work, we investigate
this issue by considering two ideal protocols, Protocol I and Protocol II. One aims at
achieving the maximum rate and the other focuses on having the best efficiency. The
theoretical results such as the distribution of modulation levels, the average achievable
rate and the efficiency of these two protocols are derived and validated through
extensive computer simulations. Furthermore, we propose a protocol to achieve the
theoretical limitation of adaptive modulation in a multinode decode-and-forward cooperative
communication system as possible. The proposed mechanism is to select
a modulation scheme and the helping relay nodes to fulfill the requirement of outage
probability while maximizing the rate and efficiency as possible. The proposed
mechanism is compared against the popular SNR-based mechanism. It is shown
that the proposed mechanism is able to provide better average rate while having
comparable efficiency to the SNR-based mechanism.
