    Abstract: 在此篇論文中,我們探討適用於非同調檢測之區塊編碼三十二點的正交振福調變(QAM),並且提出一個新的非調區塊編碼調變架構。我們推導出使用三十二點QAM 之區塊編碼的最小非同調距離,根據結果提出非同調區塊編碼三十二點QAM 架構。在相同資料傳輸率下,我們比較非同調區塊編碼十六點QAM 以及非同調區塊編碼三十二點QAM 的最小非同調距離和錯誤效能。對於不同區塊長度以及不同的構成碼,我們也針對非同調區塊編碼三十二點QAM 的錯誤效能模擬結果進行分析。 In this thesis, we focus on block-coded 32QAM (quadrature-amplitude modulation) for noncoherent detection, and propose a new noncoherent block-coded modulation schemes. The minimum noncoherert distance of block-coded 32QAM is derived, and noncoherent block-coded 32QAM (NBC-32QAM) is proposed accordingly. We compare NBC-32QAM with NBC-16QAM for the minimum noncoherent distances and error performance with same data rate. For different block length and code rate, we also analyze the simulation results of error performance of NBC-32QAM.
