| Abstract: | MC-CDMA系統在經過傳輸通道後，由於通道的影響，失去正交性，使得不同使用者間彼此產生干擾，稱之為MAI(Multiple Access Interferences)。本篇論文主要是藉由MAI功率的數學式，了解通訊碼選取對MAI功率的影響，再經由反覆過濾影響MAI功率的因素，找出最佳的通訊碼以降低MAI的干擾。 Because of the channel effect, the MC-CDMA signals will lose orthogonality and result in the Multiple Access Interference (MAI). This thesis will derive the MAI formula to get the correlation between the spreading sequence and MAI. According to this correlation, we can find the optimal spreading sequence sets to mitigate MAI. |
