在本論文中,我們以 Matlab 軟體架構出正交分頻多工 (Orthogonal Frequency Division Multiplexing, OFDM) 系統,將信號經過編碼、調變後,再加入雷利衰減通道 (Rayleigh Fading Channel) 模擬其系統效能。在本論文中分別模擬出在兩種調變 QPSK、互補碼 (Complementary Coding Keying, CCK)之下,經由雷利衰減通道 (Rayleigh Fading Channel) 的干擾來產生不同的結果。最後則個別針對有無迴旋編碼 (Convolutional Code) 之編碼技術,做系統效能模擬比較與分析。 In this paper, we implement the Orthogonal Frequency Division Multiplexing (OFDM) system on Matlab software. The transmission system have encoding, modulation, and Rayleigh Fading Channel. We simulate performances on the transmission system. In this paper, we simulate two different modulations. One is QPSK, the other is Complementary Coding Keying (CCK). The simulation system use Rayleigh Fading Channel to interference the results. Finally, we analysis and testing the system on the convolutional coding or without.
