本論文擬對一新型調變家族作一探討研究，此調變家族包含現有已存在的調變型式，如正交分頻多工（Orthogonal Frequency-Division Multiplexing），及尚未發現的調變型式，論文中即針對此新型調變家族，進行正交多工正交相位調變（Orthogonally-Multiplexed Orthogonal Phase Modulation）之錯誤更正研究。我們在論文中提出兩種機制，以適用於此各參數之調變家族，系統中以里德—所羅門碼（Reed-Solomon Codes）為通道錯誤控制碼，並以伯利肯普演算法（Berlekamp Algorithm）來作解碼，除了推導出錯誤機率外，也以電腦模擬驗證之。在論文中不但評估經過通道編碼之系統其效能趨勢，並在頻譜效率（Spectral Efficiency）相同之下，將未編碼系統與已編碼系統做一比較，進而討論編碼增益（Coding Gain）。
A novel class of Orthogonally-Multiplexed Orthogonal Phase Modulated (OMOPM) signals is investigated in this thesis. The research focus is on the application of the error-correcting block code to the OMOPM signals. The system error probability expression is derived by an exact analysis and verified by computer simulations. The performance comparison between coded and uncoded OMOPM systems is presented.
