dc.description.abstract	本論文針對一新型的調變家族--正交多工正交調變家族[4][5]使用適應性調變技術，包括可變速率可變功率、固定傳送功率以及固定調變參數三種不同的方式，在維持一定平均位元錯誤率的要求之下，根據通道狀況選擇適合的調變參數或是傳送功率，使系統有最佳化的頻譜效益。考慮非擇頻平緩衰減通道為仲上衰減通道時，找出所使用調變參數間最佳化的切換邊界以及最佳化的傳送功率。最後可發現可變速率可變功率方式會有較高的頻譜效益，但也會需要較大的傳送功率。	zh_TW
dc.description.abstract	In this thesis, we consider a novel class of Orthogonally-Multiplexed Orthogonal Modulation(OMOM)[4][5] by using adaptive modulation technique including three methods of variable-rate variable-power, constant power and constant rate. Under average bit error rate constraint, we choose suitable parameter of OMOM or transmitted power to maximize spectral efficiency according to the channel quality. Considering the frequency-nonselective, slowly Nakagami-fading channel, we find the optimal switch boundary and adapted power of each used modulation parameter. We can find that the variable-rate variable-power method get larger spectral efficiency, but it need larger transmitted power.	en_US
