    摘要: 在本論文中， 主要是利用Matlab 軟體透過正交分頻多工
    (Orthogonal Frequency Division Multiplexing, OFDM)系統通過兩種不
    同的調變技術去評估系統效能，一種是QPSK，另一種是使用互補碼
    (Complementary Coding Keying, CCK)去實現。利用不同的通道特性例
    如只加入可加性高斯白雜訊(Additive White Gaussian Noise, AWGN)
    通道，雷利衰減通道(Rayleigh Fading Channel)和通道中結合雜訊和衰
    減的影響都被考慮。假設考慮OFDM信號一個符號分別被兩個位元、
    四個位元、八個位元的雷利衰減影響系統效能，衰減特性可詳細分為
    緩慢衰減和快速衰減。
    In this thesis, it is mainly by utilizing Matlab software to evaluate the system
    performance of the Orthogonal Frequency Division Multiplexing (OFDM) system
    through two different modulation techniques, one is using the Quadrature Phase Shift
    Keying (QPSK) and the other is implemented with the Complementary Coding Keying
    (CCK). Different channel characteristics such as the channel with only Additive White
    Gaussian Noise (AWGN), channel with Rayleigh fading, and the channel with the
    combination of noise and fading effects are considered. It considers separately one bit,
    two bits, four bits or eight bits of each OFDM symbol being affected by the Rayleigh
    fading to elaborate the slow or fast fading characteristics on the system performances.
