dc.description.abstract | 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。 | zh_TW |
dc.description.abstract | 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. | en |
