| dc.description.abstract | 在本篇論文中，為了消除正交多速率調變系統在截波及時間偏移情況下的符際干擾影響，提出了符際干擾自我消除架構。正交多速率調變系統沒有採用相關性階層編碼信號，其優點是可補償功率效益的同時，又能維持較好的頻譜效益。在理想的架構上，經由擁有正交行向量的矩陣所實現的正交多速率濾波器，對於輸入的符元序列作編碼，並將輸出的符元序列加上類比的奈奎斯特脈波，即為正交多速率調變訊號。在接收端的實現上，正交多速率調變架構可以使用逐步符元偵測，如果我們所選的區塊大小N較大，將擁有較好的頻譜效益，此時與使用逐步符元偵測的理想奈奎斯特脈波調變或是可實現的方根升餘弦脈波調變架構，都有相同的錯誤效能。符際干擾自我消除架構以訊號干擾比和位元錯誤率當作系統效能的指標。缺點是會造成峰值平均功率比變大，但是根據本篇論文的分析，不至於對系統造成嚴重影響。最重要的是，使用符際干擾自我消除架構可以不用再多做通道補償，而且非常容易實現且不會造成過大的系統複雜度。 | zh_TW |
| dc.description.abstract | The orthogonal multirate (MR) modulation signal is constructed by the orthogonal multiplexing of block-precoded component modulation waveforms occupying the Nyquist bandwidth and shown to provide the same bandwidth efficiency as the nonorthogonal MR modulation signal, while giving the better error performance. The realizable orthogonal MR modulation schemes can offer the same error performance as the square-root-raised-cosine-pulsed modulation scheme, while providing prevailing bandwidth efficiencies by using sufficiently large block sizes. In this thesis, two self-cancellation schemes are proposed to suppress the effect of intersymbol interference (ISI) caused by pulse truncation and timing offset in the orthogonal MR receiver. The system performance characteristics are evaluated based on signal-to-interference ratio, bit error rate, peak-to-average power ratio and implementation complexity. It is shown that both self-cancellation schemes are effective in suppressing the effect of intersymbol interference without trading off peak-to-average power ratio (PAPR) and implementation complexity significantly. | en |
