摘要

在此本論文中, 正交-正交相位鍵移信號(Quadrature-quadrature phase shift
keying) 通過多重路徑衰減通道(Multipath fading channel)將會被分析。 在多重路
徑衰減通道中, 碼際戶擾(Inter-symbol interference)及相互碼際戶擾(Cross-symbol
interference)將會被引起。 這些效應會與信號波形有關。 因此, 位元錯誤機率(Bit
error probability)相較於Saha 與Chung 的系統在這裡將會被比較。 進一步地, 合
成-正交-正交相位鍵移信號(Dual quadrature-quadrature phase shift keying)將會被
考慮。 它傳送一組獨立的正交-正交相位鍵移信號在同一時間內以兩個盡可能靠
近的中心頻率來傳送。 因此, 次載波間相互通道干擾(Inter-carrier interference)將
會被導致。 位元錯誤機率以及頻譜效能將會在這裡被比較。 進一步地, 合成
-16QAM({16QAM}^2)信號將會被一併比較。 合成-16QAM 信號與合成-正交-正交
相位鍵移信號調變方式相似, 只是將正交相位鍵移信號改為16-QAM 信號。 它
們都有相同的位元傳送速度, 所以將會在此被一併分析。

In this thesis, the quadrature-quadrature phase shift keying (Q^2PSK) signals over
the fading multipath channels will be analyzed. In the fading channels, inter-symbol interference (ISI) and cross-symbol interference (CSI) will be induced.
Those are relative to the pulse shapes of Q^2PSK signals. Hence, bit error probability (BEP) both for SB's and CL's schemes will be compared here. Moreover,
dual-Q^2PSK signal will be considered here. It transmits two independent Q^2PSK
signal carried by two central frequencies with a close separation at the same time.
Hence, the inter-carrier interference (ICI) will be induced. The BEP and spectral
efficiency both for SB's and CL's dual-scheme will be compared here. Furthermore,
{16QAM}^2 signals will also be compared too. Like dual-Q^2PSK signals, {16QAM}^2
signals was modulated in the same way like except that two 16QAM signals are
in place of two Q^2PSK signals. Both of them have the same transmitting bit rate
and so will be analyzed here.
