dc.description.abstract | 本論文提出了一個在不改變傳送端規格下,在接收端解決深衰落的方法。由於正交分頻多工系統是於多工載波傳送,因此當遇到選擇性衰落的通道時,效能會明顯下降。當傳送訊號通過兩徑通道所產生的深衰落效應時,被深衰落的資料將完全消失,以至於接收端無法正確的把資料解回。 本論文使用一種虛擬通道法,接收端在時域先處理訊號,然後經過快速傅麗葉轉換後,處理被深衰落的訊號。此方法可以在傳送規格3/4、64QAM下,在36分貝收斂。 | zh_TW |
dc.description.abstract | This paper proposes a method in Rx for deep-fading channel with no variation Tx. Because of OFDM system is multicarrier modulation. Therefore, the performance is affected by selective fading. When the transmitted signal through pass the deep fading channel. The deep fading data will lose after FFT. This paper of contribution is resolved the deep-fading channel in Rx with no variation Tx. The performance is convergent on 36dB with the data rate 3/4 and 64QAM. | en_US |
