本論文中對正交多工正交相位調變訊號做一探討研究，而正交多工多工正交相位調變訊號包含了有現有已存在的調變型式以及尚未發現的調變型式，論文中即對正交多工正交相位調變訊號進行結合區塊編碼的效能研究。論文中提出兩種編碼機制，以適用各調變參數之調變家族。系統中以里德-所羅門碼(Reed-Solomon Codes)來保護正交群組訊號，以伯利肯普演算法(Berlekamp Algorithm)來做解碼，並結合多層次區塊編碼(multilevel block coding )於調變訊號。在論文中不但評估經過編碼之系統其效能趨勢，並且在相同或近似之頻譜效益(Spectral Efficiency)下，將未編碼與已編碼系統做一比
較，進而觀察期編碼增益(Coding Gains)。
Orthogonally Multiplexed Orthogonal Phase Modulation (OMOPM) signals are investigated in this thesis. The research is focused on the application of the block-coded OMOPM signals. In this thesis, the block-coded OMOPM systems employ Reed-Solomon codes to the orthogonal group signals which are decoded by the Berlekamap algorithm and multilevel block codes to phase modulations signals. The performance results of coded OMOPM systems on the additive white Gaussian noise channel are simulated and compared with uncoded OMOPM systems.
