摘要

合作式通訊系統是ㄧ個新的通訊技術，它可以藉由中繼站協助轉傳來提升系統效能以及降低中斷機率。增強型靜態解碼轉傳是本研究所採用的協定，我們還會結合網路編碼去探討系統的效能。
　　在此研究系統中會有一個傳送端、一個目的端、一個中繼節點。此系統傳送的方向並不是只有單一方向，一開始傳送端會傳送訊號給接收端，當接收端接收到訊號時，它會再回傳訊號給原本的傳送端。接下來中繼節點會做網路編碼並將訊號傳送給其他節點。然後我們會計算出節點的中斷機率和整個系統的中斷機率，和整個系統的分集多工權衡。

Cooperative communication system is a new communication technique. It can help transmission via relay, improve system performance, and reduce error rate.We adopt ESDF (Ehanced Static Decode and Forward) protocol for our reserch. We also combine ESDF with network coding and discuss the system perfermance.
In this reaserch, we have a transmitter, a destination and a relay. The transmission direction of our system has not only one direction. First, the transmitter transmits signal to the receiver. When the receiver receives the signal, it transmits another signal to the original transmitter. Then the relay performs network coding and transmits the network coded signal to other nodes. Then we will calculate the outage probability of the node and the outage probability of the overall system and the DMT (diversity-multiplexing tradeoff) of the overall system.
